FaL-G Bricks

• FaL-G bricks and blocks are alternative building materials to the traditional burnt clay bricks and are substitutes to the traditional burnt bricks used for construction.
• Raw materials required for manufacturing of bricks are Flyash, lime gypsum and sand (optional).
• The manufacturing process s of bricks broadly consists of three operations viz. mixing the ingredients,pressing the mix in machine and curing the bricks for stipulated period.
• Fly ash is mixed with lime & gypsum. Chemical accelerator may or may not be added to it. This mix is moulded under pressure. Air / sun drying may be done. Then this green brick is water cured.
• In presence of moisture, fly ash reacts with lime at ordinary temperature and forms a compound possessing cementitious properties. After reactions between lime and flyash, calcium silicate hydrates are produced which are responsible for the high strength of the compound.
• Production process of FaL-G bricks and blocks does not involve sintering and thus completely eliminates the burning of fossil fuels as required in the clay brick production, ultimately contributing to the reduction of greenhouse gas emissions.
