Experimental Study on Mixture Ratio and Performance of New Type of Haydite Concrete

Abstract

Lightweight aggregate concrete has the advantages of light weight, high strength, energy saving, and thermal insulation, which is widely used for building energy efficiency engineering. This thesis researches a new type of haydite concrete which is composed of Shale ceramsite and Ceramic sand. Through orthogonal test and physical and mechanical performance test, it determines the optimum mixture proportion, the relationship of dry apparent density and compressive strength. It provides the basis for the new concrete, especially in northern cold region and seismogenetic area of low-rise buildings have broad application prospects.
