Influence of Aggregate Gradation of Coarse Aggregates on Concrete Strength

Article Preview

Abstract:

Concrete is widely used in engineering construction, and studying how to improve the strength of concrete is particularly important. The coarse aggregate is one of the elements in concrete, its property affects the strength of concrete prominently. The effect of coarse aggregate size distribution on the development process of concrete strength was studied, while keeping the constant content of coarse aggregate and altering the size distribution of coarse aggregate and the water to cement ratio. The experimental results show that when the maximum aggregate size is 10mm, 20mm and 30mm respectively, the compressive strength of concrete will be increased, and the flexural strength of concrete will be reduced.
