Study on Frost Resistance of Recycled Aggregate Concrete Mixed with Rubber Powder
Publication: ICCREM 2020: Intelligent Construction and Sustainable Buildings
ABSTRACT
The recycled aggregate concrete modified by waste tire rubber is a recycled aggregate concrete made of rubber powder as admixture. The frost resistance of recycled aggregate concrete is worse than that of ordinary concrete, so the improvement of frost resistance of recycled aggregate concrete by rubber powder is studied in this experiment. According to the percentage of recycled aggregate (25%, 50%, 75%) and rubber powder (0%, 5%, 10%), different combinations of experiments were designed. The freeze-thaw cycle test was carried out by orthogonal method, and the experimental results were analyzed. The effect of aggregate content on frost resistance of recycled concrete was studied. The effect of rubber powder with different proportions on quality loss rate and relative dynamic elastic modulus of elasticity of recycled concrete was studied. The results show that rubber powder can obviously improve the frost resistance of recycled aggregate concrete, and the optimum proportion of rubber powder is obtained.
