3.4 Quarry Dust The quarry dust used for this investigation work is obtained from the quarry near tindivanam in Tamil Nadu. The quarry dust passing through 4.75 mm retained on 150 micron IS sieves are taken. Specific gravity of 2.617 and fineness modulus of 2.706 has been used. 3.5 Silica Fume The specific gravity of silica fume is 2.2.
