摘要
指出在衬砌混凝土工程中掺入适量的粉煤灰,不但能大大改善混凝土拌合物的和易性,而且使混凝土的抗渗能力有很大提高,还可以提高混凝土的后期强度,介绍了粉煤灰混凝土应用于隧道衬砌中的工程实例,结果表明满足设计"不渗、不漏、不渍"的要求。
It pointed that blending fly ash in lining concrete engineering not only improved concrete blend workability, but also enhanced largely concrete impermeability and increased concrete final strength. The engineering example of fly ash concrete applied in tunnel lining was introduced. The result indicated that which satisfied impermeable, leakproof and no-waterlogging design requirements.
