Strength and durability aspects of calcined kaolin-blended …
Blending Portland cement by 10–20% calcined kaolin by weight will not significantly alter setting time, but exceeding this range will cause a significant increase. The compressive strength of young mortars, say from 3 to 7 days, is improved by blending the Portland cement with 10% of calcined kaolin by weight.
