The geopolymeric materials was composed by sintered high alumina coal gangue-slag-soluble glass system according to geopolymer theory including preparation,test and estimate of performance,mechanism of hydration and hardening and optimal parameter of technics.

Experimental study on preparation of glass-ceramic using high-silica gangues from Fuxin,Liaoning,China;

The variation of pH value,oxidationreduction potential,sulfate content were determinted after different cultivation time for a mixture of highsulfur coal refuse and soil.

Discuss the result of coal refuse leaching test in Shanxi;

Research into trial-manufacture of rubber filer by coal refuse in Hunan Jinzhushan coal mine;

Research on modification with TiO_2 and photocatalysis features of coal refuse sintering filter material;
