摘要
纤维的掺入能有效增强超高性能混凝土的力学性能.文中从以下方面系统综述了纤维对超高性能混凝土(UHPC)的影响,纤维对UHPC的增强机理,主要包括复合材料力学理论以及纤维间距理论;总结了UHPC中各种常见的钢纤维,并阐述了其种类、形状、掺量对UHPC抗压、抗折强度以及流动性能的影响,以供参考.
Abstract
The incorporation of fibers can effectively enhance the mechanical properties of ultra-high performance concrete.In this paper,the effects of fibers on ultra-high performance concrete(UHPC)are systematically reviewed from the following aspects:(1)The strengthening mechanism of fibers on UHPC,mainly including:composite material mechanics theory and fiber spacing theory;(2)The common steel fibers in UHPC are summarized,and the effects of their types,shapes and contents on the compressive strength,flexural strength and fluidity of UH-PC are expounded.Hope to provide some reference for the future research of fiber reinforced concrete.
