摘　　要：减水剂是外加剂的一种,品种繁多,使用范围也相当广泛。选取不同的减水剂种类和不同的水灰比,通过胶砂强度试验确定这二者对水泥砂浆力学性能的影响,从而可正确适当地选取减水剂品种和确定最佳的水灰比值。Water reducing agent is one of the concrete admixtures which is various and used widely. By choosing different kinds of water reducing agent and water-cement proportions, the influence of the two factors on the cement mortar＇s mechanical property is confirmed by experiments, thus the proper breed of water reducing agent and the optimal water-cement proportion can be ascertained.
