Abstract

One new kind of cementitious material, which is suited to paste filling in coal mine, was introduced. The paste filling slurry, which is mixed with extremely small amount(about 50 kg/m3) of the material, can be solidified quickly and reach the strength requirement of none -village-relocation coal extraction engineering. The solidified body is provided with typical plasticity, high elastic modulus and strain hardening even under the condition of very small surrounding stress.
