Experimental Study on the Compression Rebound Modulus of Coal Gangue Mixture

Abstract:

This experiment was designed by making a coal gangue with coal gangue, fly ash, lime power and a small amount of cement mixture selected from Dongpang coal mine in Hanxing area.We tested the compressive rebound modulus strength of the mixture, and according to the method of uniform design, 8 groups mix ratio were designed and the experiments on the coal gangue mixture in various mix proportion have been conducted. The experimental results were analyzed by regression analysis model, and the regression equation between the compression rebound modulus of coal gangue mixture and the blending amount of each admixture was established. Finally, using this regression analysis model, the influence of the fly ash, calces, cement to strength on the compression rebound modulus of coal gangue mixture was analyzed.
