摘　　要：为探究钢纤维体积掺量对全轻混凝土力学性能的影响,设计了钢纤维体积掺量为0、1%、2%的全轻混凝土试块,对其进行抗压强度、弹性模量、劈裂抗拉强度以及抗折强度试验,并对试验现象和数据进行对比分析。试验结果表明:钢纤维能有效地限制全轻混凝土试块裂缝的发生和发展,随着钢纤维体积掺量的增加,全轻混凝土的抗压强度、弹性模量、劈裂抗拉强度和抗折强度都得到了大幅度的增加,使全轻混凝土表现出更好的变形能力和承载力。In order to explore the influence of steel fiber volume dosage on mechanical properties of full-light concrete,a test block of steel fiber volume dosage of 0,1% and 2% was designed to test the compressive strength,elastic modulus,splitting tensile strength and flexural strength,and the test phenomena and data were compared and analyzed.Experimental results show that steel fiber can effectively limit the occurrence and propagation of cracks in the concrete block,with the increase of steel fiber volume content,the light of the concrete compressive strength,elastic modulus,tensile splitting strength and flexural strength are increased greatly,make the light show better deformation capacity and bearing capacity of concrete.
