Bricks are the major building materials used in the field of construction. The most commonly used bricks are clay bricks and concrete blocks. The discharge of carbon di oxide into the atmosphere has been increasing day by day. For the production of burnt bricks, usually 22 tons of coal were burnt which produces nearly equal amount of carbon di oxide. The most vital role in terms of construction material is usually associated with Portland cement. Since the manufacture of cement leads to the liberation of CO2 in large quantity. So, an alternate is required to replace cement in the place as binding agent. Therefore, the alternative to these is the Geopolymer bricks. Geopolymers have great mechanical properties, and has the synthetic temperature of 250C to 800C. In this study, Laterite soil is used to prepare the bricks by using Geopolymer as a binding material by varying NaOH to Na2SiO3 ratio in Geopolymer precursor. Strength, durable and microstructural behavior of the brick is studied.
