| 摘 要： | 试验用RCM法研究了再生粗骨料的种类、取代率,胶凝材料用量及粉煤灰对再生粗骨料混凝土抗氯离子渗透性能的影响.结果表明,颗粒整形再生粗骨料混凝土抗氯离子渗透性能,优于简单破碎再生粗骨料混凝土,但差于天然粗骨料混凝土;再生粗骨料混凝土的抗氯离子渗透性能,随粗骨料取代率的增加而降低,随胶凝材料用量的增加而有所提高;掺加粉煤灰可提高再生粗骨料混凝土的抗氯离子渗透性能.

| Abstract: | Influence of type of recycled coarse aggregate,replacement rate,cementitious material consumption and fly ash on the resistance to permeability of chloride ions into recycled coarse aggregate concrete are studied by RCM method in this paper. The result indicates that resistance to penetration of chloride ions of particle shaping recycled coarse aggregate concrete is superior to simple crushed recycled coarse aggregate concrete,and that is lower than natural coarse aggregate concrete. Resistance to penetrati... |
