本文提出一种预测混凝土强度的简易方法,它的依据是给定一个“孔隙——固体水泥指数”即可得出一个特定的抗压强度值。对于一定范围内的空气含量、用水量或水灰比,通过本文提供的图表和列线图,可求得混凝土强度。
This paper proposes a simple method for predicting the strength of concrete, which is based on a given pore-solid cement index to obtain a specific compressive strength value. For a certain range of air content, water usage, or water-cement ratio, concrete strength can be obtained by using the charts and nomograms provided in this paper.
