Abstract :

The traditional masonry units like brick and regular cement blocks are not considered as sustainable, because it consumes fossil fuel & top fertile soil. In current situation the manufacturing of cement industries produces large extent of carbon-dioxide to nature. So we utilizes waste material such as prosopisjuliflora ash. PJA is the residue powder left after the combustion of wood. It is also difficult to decompose and also absorbs more groundwater. Therefore using PJA as a partial replacement of fly ash providing the green and clean environment. In this project a study has been carried out on manufacturing of geopolymer binder based bricks using fly ash, prosopisjuliflora ash and fine aggregate. Here the ProsopisJuliflora Ash as partially repaced to fly ash in geopolymer bricks of various percentages of 0%, 10%, 30% and 50%. Geopolymer bricks are relatively light weight and more flexible as compared to normal brick. These bricks are potentially ideal material for earthquake prone areas. The geopolymer bricks are good sound absorbent. So, these bricks can be used in auditoriums. The project result reveals that 10% of PJA enhance the compressive strength of geopolymer brick compared to other replacements. Keywords – Prosopisjuliflora ash, fly ash, sand, sodium hydroxide, sodium silicate, compressive strength.
