摘要：
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/m(3)) 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.
