Experimental Research on Durabilities of Coal Gangue Concrete

Abstract:

Basing on basic properties of coal gangue from No.1 mine of Pingdingshan Tian’an coal group, authors made coal gangue concrete with coal gangue instead of some aggregate, fly ash and slag instead of some cement. Coal gangue concrete was studied by the method of orthogonal experiment. Compression strength, its loss of strength after corrosion by sulphate, modulus of elasticity and its loss after freeze-thaw were analyzed. Optimum mix of coal gangue concrete was given by the integrated balance method. And Finally, SEM analysis on coal gangue concrete was researched. According to the experiment, Sulfate attacking on coal gangue concrete was little.
