摘要
介绍了一种适合于煤矿膏体充填的专用膏体胶结料,它可以在50kg/m3左右的极少用量条件下,保证膏体快速凝结固化,达到膏体充填不迁村采煤工程需要的强度性能.该膏体充填材料具有典型的塑性特征,弹性模量大,在低围压下就转变为应变强化特征,是一种比较理想的充填胶结材料.
One new kind of cementitious material, which is specially 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.
