概要 试图获得混凝土立方体抗压强度与水灰比、骨料级配和骨料体积浓度的关系的一般表达式。假设糊相具有由威布尔分布表示的弱点分布。结果表明，在某些条件下，推导的表达式可以简化为艾布拉姆斯定律。给出了一些实验结果，使得能够获得推导表达式中的常数。建议根据所得方程进行强度计算可能对配合比设计有一定帮助。
Synopsis An attempt is made to obtain a general expression for the dependence of the compressive strength of concrete cubes upon water/cement ratio, aggregate grading and aggregate volume concentration. It is assumed that the paste phase has a distribution of weaknesses which is represented by the Weibull distribution. It is shown that the deduced expression may, for certain conditions, be simplified to give Abrams's law. Some experimental results are given which enable the constants in the deduced expression to be obtained. It is suggested that strength calculations made from the resulting equation may be of some assistance in mix design.
