Better and cheaper cement: Optimising raw material properties

The higher residues can also increase dust loss, reduce kiln output and lead to clinker that is harder to grind and is less reactive. Figure 2 shows how even relatively small increases in raw mix quartz sand at one cement plant cause large reductions in 1 day mortar strengths once the sand addition rate exceeds 4%.
