有些读者看到本刊1981年第1期上登载的《谈谈混凝土水灰比》一文以后,提出了这样一个问题:既然混凝土中剩余的水分蒸发后形成气孔,使混凝土强度降低,那么,在混凝土中的水分应该越少越好,水越少,坍落度也越小,强度就越高。这样的概念对不对呢?用水量多、坍落度大的混凝土,就一定比用水量少、坍落度小的混凝土强度低吗?目 After reading the article “Talking about concrete water-cement ratio” published in the first issue of 1981, some readers have raised the question that since the residual moisture in concrete evaporates to form pores and reduce the strength of concrete, Concrete water should be as little as possible, the less water, the smaller the slump, the higher the intensity. This concept right? Water consumption, slump of concrete, it is certainly less than the amount of water, low slump concrete strength is low it?
