水是混凝土必不可少的组分。然而一袋94磅重的水泥实际水化所需要的水仅为2加仑(水化的水灰比为0.18-按重量计)。称之为“施工用水”的附加水是为使混凝土在施工者操作时有足够的工作度。但是,当水添加过多时,不仅混凝土的砌筑费用剧烈增加,而且混凝土往往达不到设计要求。 本文目的是为促进使用具有适当低的坍落度,但仍然可以工作的混凝土。任何一个
Water is an essential component of concrete. However, the actual hydration of a bag of 94 pounds of cement requires only 2 gallons of water (hydrated water-to-cement ratio of 0.18-by weight). The additional water called “construction water” is to make concrete work enough for the constructors to operate. However, when water is added too much, not only the cost of masonry of the concrete increases sharply, but also the concrete does not meet the design requirements. The purpose of this article is to promote the use of concrete with a suitably low slump but still work. anyone
