摘　　要：介绍混凝土外加剂的概念和作用,针对目前传统混凝土、水泥砂浆在使用过程中常因塑性及干缩等原因产生开裂现象,提出在混凝土施工过程中适当加入混凝土外加剂有助于提高混凝土的强度和密实性,改善混凝土拌合物和易性,节约水泥,防止混凝土受冻破坏。This article discusses the concept and function of concrete admixtures. In consideration of the dehiscent due to the plasticity and shrinkage of traditional concrete and cement mortar in the use process, adding appropriate concrete admixtures can improve the strength and intensity and workability of concrete mixture, saving cement and preventing concrete from being damaged.

关 键 词：混凝土 外加剂 抗压强度 抗冻性 抗渗性
