摘　　要：水工混凝土与普通混凝土相比有更高的耐久性要求,为了满足水工混凝土的特殊要求,通过试验把第三代减水剂——聚羧酸减水剂、粉煤灰、粒化高炉矿渣粉同时掺加到混凝土中,配制出高抗渗性、抗冻性等耐久性的水工混凝土,使水利工程发挥更大的社会效益和经济效益。Compared with ordinary hydraulic concrete durability of concrete have higher requirements,in order to meet the special requirements of hydraulic concrete,the third generation by test water-reducing agent-gather carboxylic acid water-reducer,fly ash and slag powders graining and mixing concrete,the permeability,high durability antifreezing of hydraulic concrete,make water conservancy project greater social benefits and economic benefits.
