Also 5% OPC in the 70% OPC + 30% fly ash blend can be replaced by 5% limestone powder resulting in the combination 65% OPC + 30% fly ash + 5% limestone powder without reducing the compressive and flexural strength at all tested ages . Both observations are important for the cement manufacturers producing fly ash blended cements.
