Abstract
AbstractThis study delves into the mechanical and durability properties of rubber fiber hydraulic concrete (RFHC) using an orthogonal testing method. The optimal mix proportion for RFHC is determined through orthogonal range and variance analysis results. The influence of polypropylene fiber content, rubber particle content, and rubber particle size on the compressive strength, flexural strength, split tensile strength, brittleness, and crack resistance of rubber fiber concrete is thoroughly examined. Durability tests are conducted based on the optimal mix ratio, and a comparative analysis of the durability between RFHC and conventional concrete is carried out. The findings indicate that the mechanical properties of the concrete exhibit a significant decline with increasing rubber content and decreasing rubber particle size. The variation in rubber content notably affects the mechanical properties of hydraulic concrete. The frost resistance and impermeability of RFHC are considerably higher than those of conventional concrete, while the erosion resistance of RFHC surpasses that of the conventional benchmark concrete. This research offers valuable benchmarks for the theoretical design and practical engineering application of RFHC, contributing to the advancement of sustainable construction materials.
