Experiment and Research on Safety Performance Analysis of Green Concrete Based on Abaqus

Abstract

Traditional concrete has weak compressive and tensile strength and low durability, which requires regular maintenance. As a new environmental protection building material, green concrete can effectively improve the compressive and tensile properties and durability of traditional concrete by introducing recycled materials and fiber-reinforced materials in the preparation process. This paper is to explore the safety performance of green concrete. The constitutive model, elastic modulus, Poisson's ratio and other data of green concrete were searched by literature. Excel was used to calculate and integrate the data, and the model was built in Apaqus software for safety test research. The research shows that: The compressive stress-strain curves of steel fiber reinforced concrete and ordinary concrete are similar to the standard curves. The deformation resistance of steel fiber reinforced concrete is stronger than that of ordinary concrete. The displacement change of ordinary concrete under the action of applied force is larger than that of steel fiber concrete, and the strength of steel fiber concrete is stronger than that of ordinary concrete. This paper can provide the corresponding data suggestions and help with the selection of materials in building construction.
