摘要
纤维混凝土用于隧道二次衬砌中,不仅可以提高混凝土的抗裂性能和耐久性能,而且可以降低工程造价。在满足规范和设计要求的情况下选用纤维素纤维进行配合比设计。对纤维混凝土的工作性能、强度、抗裂性和耐久性指标进行测试。结果表明,纤维混凝土水胶比为0.39和0.41时,可用于二次衬砌中。
Fiber concrete was applied for the seconcd lining, not only improve the crack resistance performance and durability, but also save the construction cost. With the requirement of the design and criterion,The cellulose fiber was choosed to take the mixture . The working ability,strength,crack resistance performance and durability index were tested. The results shows that the fiber concerte can be applied for the seconcd lining when the Water cement ratio is 0. 39 and 0.41.
