Abstract

The two waste products i.e. debris of heritage building and fly ash of class C category were used as a raw material for replacement of clay for making bricks. In present study the effect of Fly ash with replacement of clay mixed with different materials were studied at a constant percentage of cement i.e. 10%. Three Categories of bricks were prepared and analyzed on various parameters, the Plain Fly ash coarse sand brick (FACSB), Treated Fly ash coarse sand brick (TFACSB) and Treated Fly ash Heritage waste brick (TFAHWB). In all of the three categories the quantity of Fly ash was kept constant as 80% of the total weight. It was observed that the compressive strength of plain Fly ash coarse sand brick (15FACSB) and Treated Fly ash coarse sand brick (15TFACSB) was higher with 5% coarse sand and 15% sand combination at 10% cement. The gain in strength continues for Treated Fly ash Heritage waste Brick (10TFAHWB) and found to be higher with 10% Heritage waste and 10% sand combination. A variation in the quantity of Fly ash was also attempted and it was found that the 25TFAHWB with 50% fly ash, 25% Heritage waste and 25% sand combination at 10% cement achieved highest compressive strength.
