摘　　要：在水泥-粘土复合粉混合砂浆配合比设计的基础上利用7d强度对28d强度进行早期的推定;运用数理统计的方法,建立不同的回归方程并对结果进行比较,结果指数方程稳定性好;28d强度早期推定对建筑工程实践提供了科学依据.Based on the mixing ratio design of cement-clay composite powder mixed mortar,the 28d strength was early presumed by the 7d strength;By means of mathematical statistics,different regression equations were established and the results were compared,which indicated that exponential equation had better stability.The early presumption provides a scientific basis for engineering construction.
