Early Presumption on the 28d Strength of Cement-Clay Composite Powder Mixed Mortar


Article Preview

Based on the mixing ratio design of the cement-clay composite powder mixed mortar ,in this article,the 28d strength was early presumed by the 7d strength;by the method of mathematical statistics, different regression equations were established and the results were compared,which indicated that exponential equation had a better stability;the early presumption of 28 day strength of cement-clay composite powder Mixed Mortar provided a scientific basis for engineering construction.
