Experimental Research on Compressive Strength of Ready-mixed Concrete When Mixed with Fly Ash and Mineral Powder
Production cost and emissions of pollutants can be reduced through mixing industry waste, such as mineral powder and fly ash, into ready-mixed concrete.Two approaches are adopted to the experiments to research the effect of mineral powder and fly ash on the compressive strength of ready-mixed concrete: (1) fixing the amount of fly ash, while substituting equivalent amount of mineral powder for cement.(2) fixing the amount of cement, while increasing the amount of mineral powder and decreasing that of fly ash.The result of the experiment shows: when equivalent amount of mineral powder substitutes for 16% of the cement, the result is the best-the strength of concrete is deceased less than 5%.The experiment also concludes that: keeping the usage of cement constant and adding 10%-15% of mineral powder into concrete, the strength of concrete can be increased about 30%.
