离层注浆中粉煤灰混凝土气渗性能测试
Test of Gas Permeability of Flyash Concrete when Grouting the separated BedIn view of the performance of flyash concrete which is used as grouting material of separated bed
【摘要】 文中针对覆岩离层注浆材料粉煤灰混凝土性能问题,按不同水灰比进行了粉煤灰混凝土气渗性能测试,获得了 混凝土气渗系数与水灰比及抗压强度的关系,对深入研究离层带注浆材料稳定性,具有指导意义。K
【Abstract】 overburden,test is made according to different water-cement ratio,the relationship between gas permeability coefficient of concretek,water-cement ratio and compressive strength is derived.This proves to be of directive value to study the stability of grouting material in separated bed.
