Study on Gas Anti-Permeability of Fiber Concrete under Fatigue Loading

Abstract:

Article Preview

Cracking is the most common damage in the secondary lining concrete because of its continuous thin-walled structure, potential surrounding rock pressure and poor curing conditions. In order to improve the fatigue and gas perimeability resistance of concrete and to reduce the responding costs, four series modern concretes including ultra-fine pozzolanic powder and organic fibers are prepared and investigated. The optimized modern secondary lining concrete is determined as the concrete including 0.08% or 0.1% volume fractions of ultra-fine organic fiber (UF), based on the test results of fatigue life and coefficient of gas-permeability under fatigue loading. The result show fiber concrete is positive for enhancing the fatigue and gas permeability resistance and can apply for the tunnel secondary lining.
