摘要
本文介绍半轻质高强度钢纤维混凝土力学特性的试验研究结果。试验表明：使用石英砂能使轻质混凝土有效地获得高强度；钢纤维能明显地提高轻质混凝土的弹性模量、初裂强度和剪切强度等；在所有情况下，钢纤维的掺入能较大幅度地提高混凝土的变形能力。
This paper gives an introduction to the results of the experimental study on the mecbani/cal properties of high-strength scmi-lightweight steel fiber rein forced concrete. Tcsts show that the useof silica sand can makc thc Iightwcight concrete obtain high strength effectively lsteel fibers can increasetke elastic modulus,first cracking strength and shearing strength rcmarkably,and in all cases the addi-tion of stecl fibcrs can increase the concrctc dcformability by a rather big margin.
