STUDY AND PROPERTIES OF GEOPOLYMER ECO BRICKS

The present study’s purpose is to investigate the behavior and durability of geo polymer eco bricks made from fly ash. The bricks utilized in this investigation have dimensions of 20cm × 20cm x 40cm. Manufacturing of bricks was carried out by keeping ratio by weight of flyash to sand from river or eco-sand (silica sand) to 1:2.5. As alkaline activator sodium flume solution was used. 1:2.5 ratio of NaOH solution was taken as binder solution. 0.416 was taken as the ideal water/binder ratio which was established based on the available literature. The solution to fly ash ratio is represented by the water/binder ratio (NaOH and H2O). This research will use ambient curing to cast bricks. The blocks will be made from a variety of sands, including sand from rivers and sands containing silica also known as eco-sand. Locally available solid blocks of cement were used to perform comparative study with the results obtained in tests performed in this research work.
