We have studied and carried out the experiments on the resistance of concrete to acidic water from 1973. From 1990 we undertook the another experiment and used the concrete cylinder with 10 cm diameter and 20 cm height was used. This experiment is called as " Series 5 Test ". Its period is 5 years from 1990 to 1995. In this experiment the resistance of fly ash cement B type and sulphate-resisting cement to acidic water with pH value of about 4 have been investigated on the following factors ;(1) weight and volume change(2) density(3) ultra sonic velocity(4) dynamic modulus of elasticity(5) compressive strengthWe have only the values of the factors above measured last year. As the very few data are given, it is difficult to discuss and discribe the conclusions about the resistance of these two type cement to acidic water. But we dare say that the concrete made from fly ash cement B type has a higher resistance to acidic water than that of sulphate-resisting cement.

从1973年开始，我们对混凝土的耐酸性水进行了试验研究。从1990年开始，我们又进行了一次试验，使用了直径10 cm、高20 cm的混凝土圆柱体。这个实验被称为“系列5测试”。它的周期是从1990年到1995年，为期5年。本试验研究了B型和耐硫酸盐水泥在pH值为4左右的酸性水中的抗压性能，主要考察了以下几个因素：(1)重量和体积变化(2)密度(3)超声波速度(4)动弹模数(5)抗压强度我们仅有上述因素去年测得的数值。由于给出的数据很少，很难讨论和描述这两种水泥的耐酸性水的结论。但我们敢说，用B型粉煤灰水泥制成的混凝土比抗硫酸盐水泥具有更高的耐酸性水。
