    amount of dolomite increases in the mixture, the compressive strength decreases. The minimum amount of the compressive strength 11.19 MPa was gained when 25% dolomite powder was used in the mix 9. This showed that the compressive strength of concrete decreases as we increases the percentage of dolomite powder and nano silica
