高流动混凝土是指用于混凝土结构中 ,具有高流变性和抗分离性 ,不需振捣进行自充填的混凝土。高流动混凝土是以提高混凝土结构物的耐久性、可靠性和适应 2 1世纪新的施工技术为目的而提出的 ,是一种新概念混凝土。本文从基本性能、施工技术、工程应用角度介绍高流动混凝土 High-flow concrete is used in concrete structures, with high rheological and anti-separation, without self-filling concrete pounding. High-flow concrete is proposed for the purpose of improving the durability, reliability and adaptability of the concrete structure in the 21st century. It is a new concept concrete. This article introduces the high-flow concrete from the perspectives of basic performance, construction technology and engineering application
