全轻混凝土的工程应用发展综述

Summary of Engineering Application Development of All-light Weight Concrete

本文总结了轻骨料混凝土轻质高强、耐久性好、抗震性好、抗冻融、抗渗性能好等特点在当今混凝土发展中的应用优势,同时介绍了轻骨料混凝土的在国内外的广泛应用,最后由全轻混凝土应用过程中的骨料上浮、抗拉和抗折强度低、泵送性差等劣势出发总结了目前全轻混凝土发展的几个方面,一是纤维全轻混凝土,二是粉煤灰轻骨料混凝土,三是自密实钢纤维全轻混凝土。

This paper summarizes the advantages of lightweight aggregate concrete with high strength,good durability,good shock resistance,freeze-thaw resistance and good impermeability in today’s concrete development. At the same time,it introduces the lightweight aggregate concrete at home and abroad. Widely used,and finally from the disadvantages of aggregate floating,tensile and flexural strength, poor pumping performance in the application of all-light concrete,summed up several aspects of the development of all-light concrete,one is fiber all-light concrete,two Is fly ash lightweight aggregate concrete,three,self-compacting steel fiber all-light concrete.
