Replacement of silica sand in concrete increases from 10% to 70%, the acid cured cube strength was decreases from 4.54% to 20% for mix – 1. For mix -2 the acid cured cube strength was decreases from 6.03% to 16.66% Replacement of silica sand in concrete increases from 10% to 70%, the sulphte cured cube strength was decreases from

Even at the higher replacement level of natural sand by dolomite quarry waste in concrete samples D 80, D 90, and D 100, the increase of 16.03%, 17.84%, and 19.5% in water absorption were noted. The maximum and minimum water absorption of 3.32% and 2.67% were found, respectively, at and 0% substitution of sand by dolomite quarry waste.

Malkit Singh, in Waste and Supplementary Cementitious Materials in Concrete, 2018. 1.5.3 Setting times. The increased water content in concrete incorporating CBA as sand replacement increases the distance between cement hydration products as well as lowers the pH value of the medium which results in delay or decrease in hydration activities of the cement particles.
