用筛洗法测定混凝土的配合比,就是采取未经凝固的混凝土拌和料试样,测定其重量和其绝对密实体积,经过筛洗炒干法求出石子和砂的重量,再通过计算求出水和水泥的重量,最后计算出以水泥重量为1的实际配合比。一、基本原理我们可建立一个体积和重量的联立方程组即:
Determining the mixing ratio of the concrete by the sieve washing method is to take a sample of the concrete mixture which has not been solidified to measure the weight and the absolute compact volume thereof and then calculating the weight of the stone and the sand through the sieve washing and frying dry method Water and cement weight, the final calculation of the actual weight of cement with a mixing ratio of 1. First, the basic principles We can establish a volume and weight of simultaneous equations that:
