摘　　要：通过废旧聚苯乙烯塑料(EPS)替代砂材料,制备废旧EPS塑料/混凝土复合材料,并研究复合材料流变性能和耐侵蚀性能。结果表明:随着EPS用量的增加,复合材料的流变性能不断提高;其耐水侵蚀性能、耐二氧化碳侵蚀性能和耐低温侵蚀性能均先提高后降低;复合材料的耐高温侵蚀性能逐渐降低。当EPS用量为12%,复合材料的耐水侵蚀性能、耐二氧化碳侵蚀性能和耐低温侵蚀性能最优。Waste expanded polystyrene(EPS) plastic was used to replace sand material to prepare waste EPS plastic/concrete composites, and the rheological properties and corrosion resistance of composites were studied. The results show that with the increasing of EPS content, the rheological properties of the composites are continuously improved. With the increasing of EPS content, the water corrosion resistance, carbon dioxide corrosion resistance and low temperature corrosion resistance of the composites is increased first and then decreased. With the increasing of EPS content, the hightemperature corrosion resistance of the composites is gradually decreased. When EPS content is 12%, the composite has the best water erosion resistance, carbon dioxide erosion resistance and low temperature erosion resistance.
