随着建设项目和建设规模的不断扩大,混凝土用量呈现不断增长趋势。在现阶段混凝土使用中,对于混凝土性能的要求更为严格,不仅需要选取优质的原料进行混凝土配制,同时还要用高性能外加剂按适当比例掺入,从而使混凝土的适用性、经济性、稳定性、耐久性和强度等性能显著增加。本文对外加剂及常用种类进行介绍,对其在混凝土中的应用效果进行探析,以期为高性能混凝土的制备提供参考。
With the continuous expansion of construction projects and construction scale, the usage of concrete presents a growing trend. In the present stage of concrete use, the performance requirements of concrete are more stringent, not only need to select high-quality raw materials for concrete preparation, but also with high-performance admixture at an appropriate ratio of incorporation, so that concrete applicability, economy, Stability, durability and strength and other properties increased significantly. In this paper, the admixture and common types are introduced, and its application effect in concrete is analyzed in order to provide reference for the preparation of high performance concrete.
