摘要
根据高水材料水灰比不同其凝固后强度不同的特性,配制不同水灰比的高水材料试块,并通过单轴压缩试验研究高水灰比下高水材料固结体抗压强度与水灰比和龄期的关系,充实高水充填相关基础理论,为井下充填作业的高效开展提供指导。
According to different water cement ratio of high water material solidifying material strength after different features, preparation different water cement ratio of high water material block, and through the experimental research of high water cement ratio of uniaxial compression consolidation body of high water material relationship between compressive strength and water cement ratio, and the relationship between the compressive strength and ages, enrich high water filling related basic theory,efficient for underground filling operations to provide guidance.
