SLUMP TEST, CUBE CASTING & CUBE TESTING
CL -09
A)
SLUMP TEST : This test is conducted for determining consistency of concrete where nominal size of aggregate does not exceed 38 mm. Apparatus Used : i. Slump Cone : Top Diameter 100 mm Bottom Diameter 200 mm Height 300 mm ii. Tamping Rod : Diameter 16 mm Length 600 mm Rod rounded at one end. Procedure : The internal surface of the slump cone shall be thoroughly cleaned before commencing the test. Slump cone shall be placed on a carefully leveled metal plate, the slump cone being firmly held in place while it is being filled. The slump cone shall be filled in four layers, each approximately one- quarter of the height of the cone. Each layer shall be tamped with twenty-five strokes of the rounded end of the tamping rod. The strokes shall be distributed in a uniform manner over the crosssection of the cone and for the second and subsequent layers shall penetrate into the underlying layer. The bottom layer shall be tamped throughout its depth. After the top layer has been rodded, the concrete shall be struck off level with a trowel or the tamping rod, so that the mould is exactly filled. Any mortar which may have leaked out between the mould and the base plate shall be cleaned away. The mould shall be removed from the concrete immediately by raising it slowly and carefully in a vertical direction. This allows the concrete to subside and the slump be measured immediately by determining the difference between the height of the mould & that of the highest point of the specimen being tested. The above operation shall be carried out at a place free from vibration or shock, and within a period of two minutes after sampling.
B)
CASTING OF CUBES : Cubes of concrete should be cast regularly to estimate the strength of concrete. Concrete for filling the cubes should be taken from the middle discharge of concrete mixer. Concrete from beginning or at the end of discharge should be avoided. Cubes should be filled in 3 equal layers. Each layer should be uniformly tampered at least 35 times with a 16 mm blunt rod. Cubes should be properly leveled and finished using hand
- 15 -
trowel. Cubes should be de-molded after 24 hours and immersed in water for curing. It is important to keep the cubes away from the shocks or vibrations especially for initial 3 days of casting. We recommend that minimum 6 cubes should be taken every day and the batch of 3 cubes be tested for 7 days and 28 days respectively. As per IS 456 – 2000 minimum frequency of sampling is as follows : Volume of Concrete 1 – 5 m3 6 – 15 m3 16 – 30 m 3 31 – 50 m 3 51 and above
Number of Samples 1 2 3 4 4 plus one additional for each additional 50 m3
Each sample comprises of 3 cubes. Size of test specimens cubical in shape shall be 15 cm x 15 cm x 15 cm C)
TESTING OF CUBES FOR COMPRESSIVE STRENGTH : Cube testing is done at specified age i.e. on 7 th and on 28th day. Age of cubes is calculated from the time of addition of water to the dry ingredients. Test specimens stored in water shall be tested immediately on removal from water and while they are still in the wet condition. Surface water and grit shall be wiped off the specimens and any projecting fins removed. The dimensions of the specimens to the nearest 0.2 mm and their weight shall be noted before testing. The bearing surfaces of testing machine shall be cleaned before placing test specimen. The side faces (faces other than top & bottom) of specimen shall be placed between bearing surfaces. The load shall be applied without shock & increased continuously at a rate of approximately 140 kg / sq.cm / minute until the resistance of the specimen to the increasing load breaks down & no grater load can be sustained. The maximum load applied to the specimen shall then be recorded.
Calculation :
- 16 -
The measured compressive strength of the specimen shall be calculated by dividing the maximum load applied to the specimen during the test by the cross-sectional area, calculated from the mean dimensions of the section and shall be expressed to the nearest kg per sq.cm. Average of three values shall be taken as the representative of the batch provided the individual variation is not more than +/- 15 percent of the average. Otherwise repeat test shall be made.

PROVIDING EXPANSION / CONSTRUCTION JOINTS
CL – 23
Expansion Joint : These joints are provided to accommodate the expansion of adjacent building parts and to relieve compressive stresses that may otherwise develop. The joints formed by providing an initial gap between the adjacent building parts which gets widened or shortened while accommodating the contraction or expansion of the building. The width of the gap should be sufficient to accommodate the maximum thermal-induced moment likely to be encountered. Normally it varies between 10 mm to 40 mm. There should be complete discontinuity of masonry, reinforcement or concrete at the joint and the gap should permit unobstructed movement of the adjacent parts. Expansion joint should start from the top of footing (in case of combined footing for adjacent columns) tip topmost point of structure. Spacing of Expansion Joints : 1. Framed Structures : i) For long uniform structures at 30.0 meter interval ii) Corners of L,H,T and C shaped structures 2. Walls : i) Load bearing walls with cross walls at intervals at 30.0 m interval ii) Walls without cross walls – at 30.0 m interval. Control joints over center of openings may be
- 30 -
given at half the spacing of expansion joints.
Material used to treat expansion joints : i) Joint Filler : A strip of compressible material used to form and fill the expansion joints in structure. Joint fillers can be made out of a variety of materials such as bitumen, bitumen containing cellular material, cork strips, natural or cellular rubber, expanded plastic, mineral fiber, coconut, pith etc ii) Ceiling Compound : A material of plastic consistency applied to the joint in the form of liquid or paste. The function of the ceiling compound is to prevent the ingress of water or foreign matter. Mastic or hot-applied bituminous compound is commonly used for this purpose. iii) Water Bar : A strip which is placed across the joint during construction so as to form an impervious diaphragm. Water bars may be of natural and synthetic rubber, polyvinyl chloride or metal.
Construction Joints : Joints installed at location where construction stops for any reason is known as construction joint. If it is possible to plan construction in such a way that the days work ends at expansion or contraction joint, then there is no necessity of construction joint. But many times it is not possible to complete the concreting work in one operation. Therefore special measures are necessary to be taken to achieve perfect continuity in old and new concrete. For structural stability, it is necessary to ensure that construction joints are provided at pre-determined locations. Location of Construction Joints for different members : Slabs : For simply supported one-way slab Construction joint should be 1. vertical and parallel to main reinforcement. It can also be provided at the ¼ part part of span at right angles to main reinforcement In case of two-way slab, the joint can be provided ¼ th part of either span. Beams : In case of beams construction joint should be vertical and 2. located at ¼ th part of span. Columns : 75 mm below beam bottom. 3. R.C.C. Walls : At suitable location where erection of formwork, 4. compaction of concrete and supervision is convenient.

RAIN WATER HARVESTING
CL - 56
Due to unlimited use, sub-soil water level decreased. Due to building, roads, footpaths and concreting deposition of rain water to subsoil water is reduced. To reinstate this water bank rain water harvesting is absolutely necessary. This can be done by a)
Percolation Pit Method : Constructed in the open space at required intervals Size : 1 m x 1 m x 1.5 m Filled with broken bricks / pebbles. Suitable for sandy sub-soil area. One unit for 250 sq.ft. area (approximately)
- 70 -
b)
Bore Well Method : Roof top rain. Water may also be diverted to a bore well. A settlement / filter tank of required size to be provided. Overflow water may be diverted to a percolation pit nearby. Recharge through bore well is less effective than open wells. Defunct bore wells may also be used.
c)
Open Well Method : Rain water from the terrace is diverted to the existing open well using PVC pipes through a filter chamber. The minimum size of filter chamber is 2’ x 2’ x 2’ filled with broken bricks in the bottom and sand on the top.
- 71 -
The chamber may be covered with RCC slab
d)
Recharge Well Method (Shallow / Small) : Meant for large areas with heavy run-off Size : 3’00” diameter with 5’0” – 10’0” depth. Constructed with Brick / Concrete rings. Side walls must be perforated. Bottom (1’0”) is filled with brickbats. Covered with RCC slab / manhole. Suitable for sandy sub-soil area.
- 72 -
Note : 1. For area with clay / hard formations recharge wells with diameter (5’0”) / depth (10’0” – 15’0”) has to be constructed. 2. Run-off water diverted through a filter media preferably. 3. One wall is sufficient for areas with one ground extent. 4. Rainwater from the open spaces may be diverted through mall trenches.
e)
Recharge trench with bore method : Along the recharge trench boreholes has to be drilled. Borehole interval, 10’0” – 15’0” Suitable for clay area.
- 73 -
Notes : 1. Above structures are meant for area with large catchments like Apartments / Big Complexes. 2. RCC slab cover is optional. 3. Top (1’00”) portion may be filled with sand. f)
Recharge Trench Method : Similar to recharge pit but longitudinal in shape. Size : 0.5 – 1.0 m wide / 1.0 – 1.5 m depth. Length may vary from 1.0 m – 5.0 m Filled with broken bricks / pebbles. Suitable for sandy sub-soil area.
- 74 -
g)
Percolation Pit with Bore Method : A borehole is to be drilled at the bottom of the percolation pit. Bore hole size 150 – 300 mm diameter with 10’0” -15’0” depth. (approx.) Filled with broken bricks / pebbles. Suitable for clay area. Note : 1. Above structures are meant for area with small catchments like individual houses. 2. RCC slab cover is optional. 3. Top (1’00”) portion may be filled with sand. HANDLING, STORAGE AND

DUROCRETE MIX DESIGN MANUAL What is Mix Design ? Like any structural member concrete needs to be designed for strength and workability. Mix design consists of determining relative quantities of cement sand, metal, water to achieve the desired strength & workability. Advantages of Mix Design 1. Mix design aims to achieve good quality concrete at site economically, quality concrete means. Better Strength Better Durability Dens & Homogeneous Concrete 2. Economy in Cement Consumption : It is possible to save upto 15 % of cement for M20 grade of concrete with the help of concrete mix design. Savings in cement consumption increases with the grade of concrete. Lower cement content also results in lower heat of hydration & reduces shrinkage cracks. Design Variables in Mix Design : A. Water Cement Ratio B. Cement Content C. Proportion of Fine & Coarse aggregate. D. Use of Admixtures. Water Cement Ratio Water cement ratio (W/C ratio) is the single most important factor governing the strength of concrete. Strength of concrete depends upon W/C ratio rather than the cement content. Higher the water cement ratio lower is the strength of concrete. As a thumb rule every 1 % increases in quantity of water added reduces the strength of concrete by 5 %. A water cement ratio of only 0.38 is required for complete hydration of cement. Water added for workability over & above this water cement ratio of 0.38 evaporates leaving cavities in the concrete. They reduces the strength and durability of concrete. Hence it is very important to control the water cement ratio on site. Cement Content Cement is the core material in concrete which acts as a binding agent and imparts strength to the concrete. From durability considerations cement content should not be reduced below 290 kgs / m 3 considering moderate conditions of exposure. IS 456 recommends higher cement contents for more severe conditions of exposure of weathering agents to the concrete. It is not necessary that higher
- 106 -
cement content would result in higher strength. Higher cement content helps us in getting the desired workability at a lower water cement ratio.
A. B.
Gradation of Aggregates : Are two types Coarse aggregates (Metal) : These are particles retained on standard IS 4.75 mm sieve. Fine Aggregate (Metal) : These are particles passing through IS 4.75 mm sieve.
Proportion of fine aggregate to coarse aggregate is decided with the help of the gradation curves. The coarse aggregate of 20 mm & 10 mm are generally used for concreting. 20 mm coarse aggregate is defined as the one, which passes through 20 mm sieve and is retained on 10 mm sieve. While 10 mm metal should pass the 10 mm IS sieve and should be retained on 4.75 mm sieve. Some common problems to metal available in Pune are as follows : 1. The metal has considerable proportion of over-size aggregates varying from 20 mm to 40 mm size. Generally when the sand is fine, smaller proportion of it is enough to get a cohesive mix, while coarser the sand, greater has to be its proportion in the concrete. Excess sand increases the water requirement of concrete & reduces the strength, while under – sandy mix results in segregation and honey combed concrete. Generally sand available in Pune is very coarse (FM > 3.2) and needs to be blended with fine particles (like stone dust) to get a cohesive mix. Use of Admixtures Now a day’s admixtures are rightly considered as a fourth ingredient of concrete. Use of plasticizers is essential to control the water cement ratio on site. Plasticizers help us in increasing the workability of concrete at lower water cement ratio. Hence we can achieve much higher strength at the same cement content. Use of plasticizers is economical as the cost incurred on them is less than the cost of cement saved. This is made possible by mix design. IMPLEMENTATION OF MIX DESIGN ON SITE Items necessary on site for Mix Design. 1. Set of 12 cube moulds. 2. A slump cone, tamping rod, and a scale. 3. Weighing balance of 5 kg with accuracy of 2 gms. 4. Spring balance of 50 kgs 5. Buckets of known capability for addition of water preferably 5 to 7 liters in capacity 6. 250 ml measuring cylinder. 7.

IMPORTANT FOR IMPLEMENTATION OF MIX DESIGN
1. 2.
Cement brands to be used should be standardized in advance. Make regular corrections on the proportions of mix design for a) Moisture in sand b) Absorption by metal c) Bulk density of sand d) Changes in fineness of sand Regularly check the weight of cement bags. The water cement ratio on the site should be strictly controlled. The water cement ratio can be controlled by maintaining the slump as per the design specifications. The slump readings should be taken after every 25 bags of concreting. The slump readings should be specially taken for the batches from which cube casting is done. Cement bags to be used should not be older than one month. Cement used should not have lumps and should give a cool feel on hand. Extremely coarse sand or silty sand should not be used.

STANDARD CORRECTIONS FOR IMPLEMENTING MIX DESIGN
3.1
Corrections for surface moisture in sand. Sand contains some fraction of water as surface moisture. This moisture affects he water cement ratio of concrete. Water cement ratio takes into account the total water available for hydration of cement.
- 108 -
Water cement ratio = (water added per batch + Surface moisture in sand – absorption of coarse aggregate) / 50 Finding surface moisture of sand Take 500 gms of sand & hat it in tray gently till sand is dry and starts flowing freely. Surface dry sand is weighed again to find the loss in weight. Surface Moisture = W / (500 - w) Note : It is important not to over heat the sand To get a rough estimate of surface moisture following thumb rule may be used when sand is not extremely wet. Moisture in Sand
1% 2% 3% 4% 5%
Bulkage Medium Sand 8% 16 % 22 % 27 % 29 %
Coarse Sand 6% 12 % 15 % 17 % 18 %
Water to be added per batch = (water cement ratio * 50) – Surface moisture * wt. of sand per batch If moisture content = 4 % Wt of sand = 135 kgs Water-cement ratio = 0.55 Water to be added per batch = 0.55 * 50 – 4 % * 135 = 27.5 – 5.4 = 22.11 liters Weight of sand per batch should be increased correspondingly by wt. of surface moisture in sand e.g. 5.4 kgs Moisture content in sand will vary from day to day and also with different lots of sand. It is therefore very important to make corrections for moisture in sand to maintain w/c ratio. If slump on site is kept under control, the water cement ratio is automatically controlled. FINDING AGGREGATE ABSORPTION :
- 109 -
For any mix design, the coarse aggregate is considered to be in saturated surface dry condition. Whereas the metal on sites is often in bone dry condition (especially in summers). This dry aggregate often absorbs the water added in concrete & reduces the workability of concrete. Correction for surface absorption is necessary to maintain the water cement ratio. A correction of 1 % to 2 % of coarse aggregate may be made in case of bone dry condition of aggregate. For example if the aggregate absorption is 2 % and water and total weight of aggregates is 180 kgs then Aggregate absorption = 0.02 * 180 = 3.6 liters. Hence quantity of water added (from previous example) = 22.1 + 3.6 = 25.7 CORRECTION FOR BULK DENSITY : Every mix design is always done considering weights of different ingredients. In case volume batching is done on site, the weights of aggregates need to be converted into volumes. This is done with the help of bulk densities of aggregates. Bulk density = weight of material in kgs ----------------------------volume in liters Bulk density can be measured on site by filling a standard 35 liters pharma with aggregate & weighing the aggregate filled in the form. e.g. wt. of sand in 35 liters pharma = 58 kgs Bulk density = 58 / 35 = 1.66 kgs / liters. Volume of sand per batch = wt. of aggregate per batch -----------------------------Bulk density VOLUME BATCHING For example, if weight of sand per batch = 135 kgs. Volume of sand = 135 / 1.66 = 81.3 liters, say 80 liters. Hence use 2 forms of 25 liters & one form of 30 liters. Bulk density of sand changes with bulkage. Hence correction for bulk density of sand should be made every day. Bulk density of metal is between 1.4 kg / lit to 1.5 kg / lit whereas bulk density of sand varies with bulkage and usually lies between 1.6 to 1.8 kg / lit. CORRECTION FOR BULKAGE : This is done in case of volume batching of concrete. When sand is moist it bulks i.e. it occupies greater volume. Hence, less weight of sand is taken in the given volume. In other words, the bulk density of sand
- 110 -
changes. If correction of bulk density is done. Otherwise, volume of sand needs to be increased in proportion of bulkage. Measuring bulkage on site Take 100 mls of sand in 250 ml. Baker and add water so as to completely submerge the sand. Shake the beaker well and keep it steady for some time. Note the level to which it settles. Bulkage % = Original Level - New Level * 100 ----------------------------------------- New Level CHECK THE SILT CONTENT : Excessive silt in sand affects the bond between cement and sand. This reduces the strength of concrete. This problem is quite severe during monsoon. Measuring silt content on site. Take 50 ml of water in 250 ml beaker and add some salt to it. Add sand to it till 100 ml mark is reached. Again add water up to 150 ml. Stir the sand well to wash it in salt water. Keep the beaker still for 3 hours. Observe the thickness of silt layer. Silt content = Height of Silt Layer (ml) * 100 -----------------------------------Height of Sand Sand with silt content greater than 7 % calculated by above method should not be used for concreting.
CORRECTIONS FOR CHANGES IN GRADATION OF SAND : Sand shows lot of variation on sites because of changes in source of supply. The fineness module of sand in Pune varies from 3.2 to 3.8. The IS specifies a limit of 2.2 (fine sand) to 33.2 (coarse sand) for fine aggregate. This means that sand available in Pune is extremely coarse. This is partly because of absence of fines in the sand and 10 % to 15 % is retained on 4.75 mm sieve as chal or shingle present in the sand. Hence, in case of extremely coarse sand, use of stone dust up to liters is recommended. If sand available on site is coarser than the one used for mix design, following correction may be made. A. WEIGHT BATCHING i. Increase in the weight of sand up to 15 kgs and reduce the weight of metal by equal quantity. Total weight of aggregate going per batch
should remain constant. ii. If the mix does not improve with above correction, replace up to 15 kgs of sand by dust in the weights mentioned in the design.
- 111 -
B. VOLUME BATCHING i. Increase the volume of sand by 10 liters and reduce volume of metal by 10 lit. ii. If the mix does not improve with above correction replace 10 liters of sand in mix design proportion by 10 lits of dust. Following precautions should be taken when stone dust is to use. •
•
•
Stone dust should not be too fine or powdery ( FM should be between 2.0 to 2.5 ) It should be used used in limited quantity as mentioned above unless, higher quantity is recommended by the laboratory. Strict control on water cement ratio should be kept. Stone dust reduces the workability; hence the water cement ratio is likely to increase. The slump may be maintained 2 cms below the value given in the mix design.
Note : If above corrections in the proportion do not yield satisfactory mix, fresh trial should be conducted at the laboratory for a revised mix design.
