Q: What are joints in concrete? Why are they necessary? A: Joints A: Joints are pre-planned cracks to accommodate the expansion and shrinkage of concrete, caused by changes in moisture and temperature. Although irregular cracks are unsightly and difficult to maintain, they generally do not affect the integrity of the concrete. Cracks in concrete can be controlled and minimized by properly designed joints. There are three types of common joints: 1. Contraction joints 2. Isolation or expansion joints 3. Construction joints Q: Why does concrete crack? A: Concrete, A: Concrete, like all other materials, will slightly change in volume when it dries out. Q: How does temperature affect concrete? A: Three factors control the set time, strength gain and overall durability of concrete: time time,, temperature and temperature and moisture moisture.. These factors are interdependent on each other. The ideal temperature for concrete is 10oC. C. If If the temperature is too high, the concrete can dry out prematurely and not reach its desired strength. It can also crack from rapid shrinkage. If the temperature is to low, the concrete set time and strength gain can be reduced and the concrete can be subjected to freezing while water i s present and have severe freeze/thaw damage. Q: Why is curing necessary for concrete? A: Concrete A: Concrete develops strength ONLY in the presence of moisture, therefore it is absolutely important that it is kept moist after casting. If concrete is allowed to dry out, it will not develop to the strength it was designed for. Q: What are the causes of Honeycombing? A: Honeycombing A: Honeycombing is caused by a number of different reasons: 1. Insufficient compacting or vibrating 2. Segregation of the concrete when it i s allowed to free-fall from heights over three feet

When the formwork is not nailed tight and the grout from the concrete leaks out 5. When too stiff a concrete is used without the proper vibrating equipment Q: What is segregation? A: Segregation A: Segregation is the separation of coarse aggregate from cement paste. It mainly occurs due to excess water, resulting in the non-cohesiveness of concrete. Q: What is workability of concrete? A: The ease of placing, compacting and finishing of concrete in t he desired manner is its workability. Normally the workability is measured through slump; higher the slump, higher the workability
