Experimental Study on the Combined Aggregate Concrete Strength
From the experimental research, the cube compressive strength and prism compressive strength of combined aggregate concrete are compared. Based on regression analysis, the influence of different substitution ratio of lightweight aggregate, age of concrete and water-cement ratio are studied, and the age coefficient is analyzed. According to the test results, the formula of compressive strength of combined aggregate concrete is given.
