摘　　要：为探究不同纤维种类对全轻混凝土抗压力学性能的影响,本文基于标准养护条件下掺入钢纤维(掺量0、0.5%、1.0%、1.5%、2.0%)、玻璃纤维(掺量0、0.5、1.0、1.4 kg/m^3)的全轻混凝土抗压力学性能展开试验研究。结果表明,钢纤维、玻璃纤维的掺入能提高全轻混凝土的抗拉性能,从而克服并减少全轻混凝土内部微裂缝的产生。钢纤维的掺入对全轻混凝土抗压提高贡献成正比,而玻璃纤维掺量为0.5kg/m3时全轻混凝土的抗压强度要高于其他掺量。In order to explore the influence of different fiber types on the compressive properties of lightweight concrete, the anti compression mechanical performance of lightweight concrete mixed with steel fiber（doped amount of 0、0.5%, 1.0%, 1.5% 、2.0% ） ,glass fiber（doped amount of 0、0.5 、 1.0,1.4kg/ m^3）were discussed and studied under standard curing condition. The results show that the incorporation of steel fiber and glass fiber can improve the tensile properties of all lightweight concrete, so as to overcome and reduce the occurrence of inner micro cracks in all lightweight concrete. The incorporation of steel fiber is proportional to the contribution of compressive strength of all lightweight concrete, while the compressive strength of lightweight concrete is higher than that of other kinds of concrete when the content of glass fiber is 0.5kg/m^3.
