2017-2-2 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.

2021-6-4 investigated the partial replacement of sand with quarry dust. Initially cement concrete cube was studied with various proportions of cement concrete + quarry dust (M 20, AND M25). The experimental results showed that the addition of quarry dust as fine aggregate ratio of 30%, 40% and 50% was found to enhance the compressive properties.

2020-3-20 The incorporation of quarry dust at a slag/cement replacement ratio up to 20% has a little detrimental impact on the compressive strength at 28 days. Instead, the addition of quarry dust seems to increase the compressive strength development rate at early curing ages, which possibly attributes to
