摘　　要：假设标准养护28d混凝土强度、加速养护混凝土强度服从正态分布,由早期推定混凝土强度的误差服从正态分布,可推算出早期推定混凝土强度的均值和标准差,并用其作为混凝土质量控制图的参数,制作控制图以控制混凝土的质量。If28day strength of concrete under normal curing and the strength of accelerated curing present -ed canonical distribution,and the inaccuracy of early predicted concrete strength is also presented canonical dis-tribution,the average and standardized difference value of concrete early strength may be pre dicted.These values could be used as parameters of concrete quality control chart,by which quality of con crete can be controled.
