摘　　要：从混凝土坍落度损失与控制机理入手 ,研制出控制坍落度损失的添加剂 ,能增大水泥净浆的流动度 ,并能控制流动度损失 ,且硬化后混凝土质量与基准混凝土相同。Starting with the loss and control mechanism of concrete slump, an admixture to control loss of concrete slump has been duly manufactured. This admixture can increase the fluidity of plain cement mortar and control its loss of fluidity. In addition, after concrete setting, the quality of concrete has been confirmed good and identical as that of standard concrete.
