Introduction

AAC is Autoclaved Aerated Concrete. The blocks are made to aerate by creating a reaction between silica in base material such as fly ash or sand, active lime, and aluminum power. The block hardness is being achieved by cement strength, and instant curing mechanism by autoclaving. Gypsum acts as a long term strength gainer. The finished product is a 2.5 times lighter Block compared to conventional Bricks, while providing the similar strengths. The specific gravity stays around 0.6 to 0.65. This is one single most USP of the AAC blocks, because by using these blocks in structural buildings, the builder saves around 30 to 35 % of structural steel, and concrete, as tese blocks reduce the dead load on the building significantly. The major raw material………..Fly-Ash, an indispensable by-product of Thermal Power Plants, is an environmental threat across the globe. Power plants are facing an ever increasing challenge disposal of this polluting agent. This unit is proposed to manufacture AAC Bricks & Blocks by consuming the Fly-Ash as one of the prime raw material. Secondly, it also helps environment by saving the i nvaluable top soil by not using them in brick making like conventional brick making. Thirdly, they need no burning, thus further enhancing their Eco-Friendly Brand. The steam curing requires far less fuel, compared to the backing for each cubic meter of Bricks. This is the reason these bricks are also referred as Eco Bricks or popularly Green Bricks, (though the color is gray). AAC Blocks are largely used in various constructions, such as load bearing and pillar structure Buildings, Boundary walls, Roads, Culverts, Pavements, and wherever conventional bricks can be used. The general AAC blocks fall in the strength zone of 302 60 Kg/Cm , thus is having comparable strength as conventional Bricks, and hollow concrete blocks. These Blocks gain strength over a period of time up to 2 years, where as the conventional bricks tend to lose strength over a period of time. These green bricks can attain very regular and uniform shapes. As no burning is involved, so the shape also remains unchanged. As a result, the final Brick work with these green bricks consumes less mortar to build, less mortar to plaster. Further, the AAC being a concrete itself, it forms a more uniform bond with cement mortar, giving almost a homogeneous structure. Not only this, even exposed brickwork (without plastering) is a good durable structure. So people prefer to leave the Green Bricks Brickworks in garages, boundary walls etc. un-plastered.

Market

Shelter is third skin, according to a German Concept, which implies it’s importance next to human Skin and Clothing. This also shows the attachment of human race to this fundamental requirement. Building Material accounts for major component of the construction cost. Depending on the location they can contribute to 60 - 70 % of the cost of construction. With the ever increasing population, the demand for housing increases. This directly creates demand for this prime commodity of building. Add to the above fact the nearby area of this project site is undergoing a major infrastructure revolution. As Residential, Commercial, IT companies, and Industrial establishments are coming in, we can conclude that the Blocks unit will prosper and flourish in this environment. There is a central government gadget notification mandating government departments and CPWD to use 100% Fly Ash based Bricks in their all constructionsdirectly of through contractors. This factor will help the marketability of this product immensely. Fly Ash policy of the Government also mandates that 20% of Fly ash Generated by a power plant must be given free of cost to SME sector on a priority basis.

Carbon Credits Estimates

AAC blocks are being seriously considered for CDM projects in India for earning Carbon Credits. As the CER Generated is also relatively less, four or five such units can be bundled together to make a Group CDM in the same sactors. This project is likely to generate 1 CER per each 7 or 8 Cubic Meter of Blocks production, depending on, and subject to the CDM methodology adopted, and the interpretation of additionality and baseline parameters by the validating authority. Just for a rough estimate of CERS, for an annual production of average size AAC plant, that is 100000CM/Annum, we are likely to get around 12500 CERs on full capacity Production. At present market rate of 11.5 Euros per CER and @ Rs. 60 per Euro, we can expect to get additional revenue on CER. But we must expect to take a cut of around 20 to 30% of CERs, if we want to forward sell the CERs and get the CDM part sponsored by the buyer.

Raw Materials, Sources and Availability.

Fly-Ash:

A lot has been said about this raw material in this Project Profile itself. But this Raw material is freely available in Thermal Power plants. There are no taxes on this item whatsoever. Transportation charges are only to be attended by the entrepreneur.

Lime:

Active powered lime is a requirement for giving the real aeration to the product. In phase 1 we can aim to buy the acti ve lime directly. In phase -2 we can think of having backward integration and making a lime powering unit at site to have a more competitive advantage, We can also think of a lime burning klin inside the factory premises. The project financials however have not considered the costs of powering unit, and the lime kiln in this project. Different qualities of lime are available, and depending on the raw materials, the mix design can be chosen to get the optimal quality of production. OPC. This Project aims to utilize OPC cement as main binder material. It will give faster strength to the bricks, besides giving improved consistent quality. It also ensures a better cost effectiveness for the same. Using OPC will be a standardized practice. The other prime advantages of using OPC (compared to other binders) is it’s easy availability locally through nationwide Retail Network of Cement Companies.

Gypsum:

This too is an industrial waste. This is available as an industrial byproduct of Fertilizer Plant. Gypsum is responsible to give long term strength to the Blocks.

Aluminum Power .

Finely ground Aluminum power is used in very limited quantity ( less than 0.5%), so that it reacts with active lime, and silica in base material to make the aeration, and swell the product, making it very light weight product.



8.

Process The Process of manufacture is simple t follow, and complex to implement.

First, the Fly Ash is mixed with water, and made Slurry in a slurry mixture. If Sand is used as a base material, we need a ball mill to grind the sand to fine power. The slurry making process is same sand. After Slurry is made, the slurry is stored in slurry storage tank, where the slurry is constantly agitated. Care is taken to run the slurry storage tank all the time, so that is never settles down the particles. Then a weigh batcher weighs the Slurry, lime, OPC, Gypsum and aluminum power in preset quantities, and mixes thoroughly. The mixture also pours the mix into the Mould carried n the mould cart. The full pouring of the mixture is just enough to fill around 50% of the mould. Then the mould is kept in a warm c hamber for 2 hours, so that the aeration and the light initial setting takes place. Next process is de-molding process of the big block, in which a sophisticated overhead hoist takes the mould, demoulds the block. Next process is the level wire cutting of the Block, while the block passes on the cutting trolley through the series of wires. This process follows a vertical wire cutting where as the block remains stationary, and the cutter cuts the block vertically. The final cut blocks are Steam cured in autoclaves for 8 hours at 12 KG/Sq cm pressure, and 200D C The product is ready on the same date to go into the market.
