目前混凝土和钢筋混凝土制品和构件多数情况是在70—90℃常压下蒸养制作的。为加速混凝土硬化和减少水泥用量,曾研究在混凝土中掺入带活性的矿物外加剂,试验得知掺硅藻土有较好的效果,它可以节约1/3以下的水泥,加速混凝土蒸养,提高混凝土的强度和容重。在苏联储存有大量的硅藻土,仅欧洲地区 At present, most concrete and reinforced concrete products and components are produced by steaming at 70-90°C under normal pressure. In order to accelerate the hardening of concrete and reduce the amount of cement, it has been studied to incorporate active mineral admixtures in concrete. The experiment shows that the use of diatomaceous earth has better results, it can save 1/3 of the following cement, and accelerate the steaming of concrete. , Improve the strength and bulk density of concrete. There is a large amount of diatomaceous earth in the Soviet Union, only European regions
