摘　　要：为探究玻璃纤维掺量对混凝土流动性及力学性能的影响,在混凝土中分别掺入不同掺量的普通玻璃纤维、耐碱玻璃纤维,测定了玻璃纤维混凝土的流动性、抗压强度、抗折强度。结果表明:混凝土的流动性随着玻璃纤维掺量的增加而逐渐降低。玻璃纤维改善了混凝土的抗压与抗折破坏形态,提升了混凝土的抗压强度和抗折强度,当耐碱玻璃纤维掺量为9kg/m^3时,混凝土的抗压强度提升了23.5%。当耐碱玻璃纤维掺量为6kg/m^3时,混凝土抗折强度提升了43.9%。In order to explore the influence of glass fiber on the fluidity and mechanical properties of concrete,different amounts of ordinary glass fiber and alkali resistant glass fiber were added into the concrete,and the fluidity,compressive strength and flexural strength of glass fiber concrete were measured.The results show that the fluidity of concrete decreases with the increase of glass fiber content.Glass fiber improves the compressive and flexural failure modes of concrete,and improves the compressive strength and flexural strength of concrete.When the content of alkali resistant glass fiber is 9 kg/m^3,the compressive strength of concrete increases by 23.5%.When the content of alkali resistant glass fiber is 6 kg/m^3,the flexural strength of concrete increases by 43.9%.
