通过对150 mm×150 mm×150 mm的立方体标准试件进行耐磨性试验,全面地比较和分析了再生粗骨料的取代率、水胶比、砂率、胶凝材料的总用量对再生混凝土耐磨性能的影响规律,并分析了其产生的原因。结果表明,确定适宜的再生粗骨料取代率对再生混凝土耐磨性能具有重要意义,水胶比对再生混凝土耐磨性影响最显著,砂率和胶凝材料的总用量对再生混凝土耐磨性有一定的影响,同时试验结果可为以后再生混凝土耐磨性研究提供一定的参考。
Through the abrasion resistance test of 150 mm × 150 mm × 150 mm cubes, the replacement ratio, water-binder ratio, sand ratio and the total amount of cementitious materials were compared and analyzed comprehensively for the regeneration The law of wear resistance of concrete, and analyzes the reason of its occurrence. The results show that it is of great importance to determine the appropriate replacement rate of recycled coarse aggregate to the wear resistance of recycled concrete. The water-binder ratio has the most significant effect on the wear resistance of recycled concrete. The sand ratio and the total amount of cementitious material Have a certain impact, at the same time, the test results can provide some reference for the study of wear resistance of recycled concrete in the future.
