    Sandstone Wastes As Aggregate And Its Usefulness In Cement

    Jan 01, 2018 Kumar et al. studied the effects of fire on concrete containing quartz sandstones as coarse aggregates in concrete. He observed a maximum loss of compressive strength (80%) for the control concrete (made from natural aggregate) at 800 C for 0.45 water-cement ratio. A minimum loss of 66% was observed for concrete with 100% quartz sandstone ...
