摘　　要：混凝土缓凝剂除了具有抑制水泥水化作用,延长混凝土凝结时间以外,还具有辅助塑化效应和增强效应。不同缓凝剂的辅助塑化效果及成本不尽相同,本文尝试在掺加不同高效减水剂的混凝土中,复合两种缓凝剂,在保证缓凝效果的前提下,提高缓凝剂的辅助塑化效应,以降低复合外加剂成本,提高混凝土强度。Concrete retarder has auxiliary plasticizing effect and auxiliary enhancing strength besides preventing the hydration of cement,leading to longer setting and hardening time of concrete.Because effect and cost of the different retarder auxiliary plasticizing are different,this paper attempts to compound two kind of retarders in mixes adds the different super plasticizer in the concrete,under the premise of guarantee the effect of slow congeals,enhances the auxiliary plasticizing effect,reduces the cost of co...
