Abstract

Concrete is one of the important materials in engineering construction. The uniaxial compression experiment reflects its bearing capacity and deformation performance, which is an important method for concrete material properties research. In this paper, the traditional uniaxial compression experiment is used to study the mechanical properties of concrete. Firstly, according to the composition of concrete material, the mortar strength experiment, aggregate content experiment, and aggregate proportion experiment are designed. Then, the standard cube concrete specimens of two-graded are formed according to the experiment design, and the specimens are under standard curing condition in accordance with the requirements of the concrete test specification. The hydraulic servo system is adopted to conduct the uniaxial compression mechanical experiment. The stress-strain curves and damage processes of the mortar specimens as well as concrete specimens under uniaxial compression are obtained. Finally, the experimental results reveal the influence of the water-binder ratio, aggregate content, aggregate proportion on mechanical properties under uniaxial compression, and the reasons are explained and analyzed. The research results have reference value for understanding concrete material properties and benefit to guide concrete structure design.
