- •
Quartz sandstone (a mine waste) is used in cement concrete as a replacement of natural coarse aggregate.
- •
M30 grade of concrete was used for the study with water cement ratios of 0.38 and 0.4.
- •
Clay content analysis and its impact on compressive strength were studied.
- •
Different blending ratios of coarse aggregates were studied to obtain the best packing and enhanced compressive strength.
