高瓦斯隧道中的高性能气密性混凝土技术

High performance and gas-tightness concretes technology in the high gas tunnel

介绍了高瓦斯隧道中的高性能气密性混凝土技术和气密性原理,通过正交试验选择工作性能、强度、抗渗性、电通量、耐蚀性、气密性均能满足要求的配合比数据并进行了结果分析。经实践检测满足了工程混凝土高性能和气密性的双重标准,保证了施工和运营中的安全和耐久要求。

Introduced the high performance and gas-tightness concretes technology in the high gas tunnel and the principle of gas-tightness, se- lected the concrete mixture data whose work performance,strength,Anti-permeability,electric flux,corrosion resistance,gas-tightness all can meet the requirements by orthogonal experiment and analyzed the results.It satisfied the high performance and the gas-tightness double standards of the engineering concrete by practice, and ensured that the construction and operation of the safety and durability requirements.
