摘要
本文论述了轻骨料混凝土的发展历程,指出了轻骨料混凝土用于承重结构时的弊病。使用纤维增强轻骨料混凝土,能有效提高轻骨料混凝土的力学性能,使混凝土的抗折、抗裂、抗渗及韧性等性能得到不同程度的改善。在保持轻骨料混凝土质轻特征的前提下,将聚丙烯纤维掺入轻骨料混凝土并用于承重结构将是今后的发展方向。
This paper discusses the course of development oflightweight aggregate concrete, and points out that the short-comings of lightweight aggregate concrete for load-bearingstructure.Fiber reinforced lightweight aggregate concrete, caneffectively improve the mechanical properties of lightweight aggre-gate concrete, and improve the performance of bending, cracking,impemeability and toughness of concrete varying degrees.Underthe premise of maintaining the lightweight chara- cteristics of lightweight aggregate concrete,, the ineorporation of polypropylenefiber in lightweight aggregate concrete for the load-bearing structurewill be the future direction of development.
