Experiment Study on the Compressive Strength of Combined Aggregate Concrete

Abstract:

Base on the experiment, the cube compressive strength of the combined aggregate concrete is studied in the paper. The results show that the strength of combined aggregate concrete increases with the decreasing amounts of lightweight aggregate, and the water-cement ratio and the replacement ratio of lightweight aggregate are the main factor on the strength of combined concrete. According to the experiment results, the formula of the compressive strength of combined concrete is given.
