理论上混凝土的最佳水灰比为0.2左右,该知识在多年前就被大众所熟知。但对于大多数预制混凝土制造商来说,0.25的水灰比无法满足搅拌均匀和密实过程顺利完成。湿润集料需要一部分水,这意味着水灰比0.35~0.5时才能获得良好的搅拌和密实成型条件。本文介绍混凝土路面砖生产中,新拌混凝土含水率对制品性能的影响关系。 In theory, the optimum water-cement ratio of concrete is about 0.2, which was well known to the public many years ago. However, for most precast concrete manufacturers, the W / C ratio of 0.25 can not meet the requirements of uniform mixing and compacting. Wet aggregate requires a portion of the water, which means that good mixing and dense molding conditions are achieved when the water-cement ratio is 0.35 to 0.5. This article describes the concrete pavement brick production, fresh concrete moisture content of the relationship between product performance.
