In order to verify the feasibility of smelting slag gelling materials being used in full tailings paste filling in mines,the method of soaking paste block in aqueous solution is employed. The indexes of water samples in different curing cycles are tested,and the compressive strengths of soaking curing and standard curing paste blocks are com-pared. The experiment results show that slag gelling materials replacing part of cement used,unlike full cement full tailings paste filling,will do no harm to underground water;during the growth of paste filling block strength,the final block intensity suf...
