- •
Quartz sandstone (mine waste) is used in cement concrete as a replacement of conventional coarse aggregates.
- •
M30 grade of concrete was used for the study with varying water cement ratios of 0.35, 0.4 and 0.45.
- •
Quartz sandstone concrete showed a considerable thermal resistance.
- •
Minimum loss of compressive strength was observed to concrete samples under fire exposure.
