Preparation of Coal Gangue Cement Mortar

Abstract:

Many researches on coal gangue are aimed at increasing its activity by many methods together such as thermal, mechanical and chemical. The methods are so complex that they are difficult to be adopted by some companies. In this paper, considering the low-strength requirement of cement mortar, the activity of coal gangue is more evidently shown by Ca(OH)2 activator. The 28-days strength of coal gangue cement mortar can reach 18MPa and the hydrated mortar shows and keeps an expansive behavior by adding methyl cellulose ether and CaSO4•2H2O at all the ages.
