混凝土立方体抗压强度通常是用以判断混凝土质量的主要参数之一。用混凝土立方体抗压强度评定混凝土质量好坏的数量标志是混凝土强度的平均值和标准差或变异系数。前者反映混凝土强度达到的平均水平;后者表示混凝土强度的离散程度。这两个指标的大小可反映出混凝土生
The compressive strength of concrete cubes is usually one of the main parameters used to determine the quality of concrete. The amount of concrete used to evaluate the quality of concrete cubes compressive strength marks the average and standard deviation or coefficient of variation of concrete strength. The former reflects the average level of concrete strength; the latter represents the degree of dispersion of concrete strength. The size of these two indicators can reflect the concrete
