- Abstract
The present study focuses on utilizing stockpiled dolomite quarry waste for sustainable and cleaner production of concrete. Natural river sand is substituted with dolomite quarry waste at 0, 10, 20, 30, 40, 50, 60, 70, 80, 90, and 100% in concrete mixes. The test findings revealed the concrete mix made with 10% dolomite quarry waste displayed mechanical strength comparable to the control concrete mix. The concrete compressive strength and elastic modulus decreased slightly by 3.30% and 2.40%, respectively, at the 10% substitution of natural river sand. A mathematical model for predicting the compressive strength, elastic modulus, and other properties of concrete was also developed in the study. Water absorption, sorptivity coefficient, and carbonation depth increased by 2.90%, 4.16%, and 5.80%, respectively, and ultrasonic pulse velocity and surface resistivity of concrete decreased by 0.76% and 6.25%, respectively, using 10% dolomite quarry waste. Modified concrete containing dolomite quarry waste at all replacement levels showed improved resistance in the sulphuric acid attack. Furthermore, the study's overall outcomes revealed that dolomite quarry waste had a good sustainability performance with a lower environmental impact than conventional concrete.
