摘 要:试验探究了纤维素纤维对混凝土工作性能、基本力学性能、耐久性能的影响。结果表明,掺加纤维素纤维对混凝土流动性能影响较小,但对提高混凝土抗压强度及抗拉强度有一定作用,掺加1.5kg/m3纤维素纤维的混凝土抗压和抗拉强度分别提高6.62%、17.99%。纤维素纤维的掺加有利于改善混凝土抗渗性能及抗冻性能。
Abstract:The effect of different content of cellulose fiber on the working ability, basic mechanical properties and durability of the tunnel lining concrete were studied. The results showed that the addition of cellulose fiber has little effect on the flow performance of concrete, but it has a certain effect on compressive strength and tensile strength of concrete. The compressive and tensile strength of concrete with 1.5kg/m3 fiber increased 6.62% and 17.99% respectively. Adding cellulose fiber is help for improving impermeability and frost resistance of concrete.
