摘要
采用人造海水对再生混凝土试件进行加速腐蚀试验,研究再生混凝土抗压强度随腐蚀时间的变化规律。结果表明:随着粉煤灰掺量的增加、再生粗骨料取代率的降低,再生混凝土抗海水侵蚀的性能增强;再生混凝土56d抗压强度与胶水比之间呈较好的线性关系;随着腐蚀时间的延长,再生混凝土抗压强度与胶水比之间呈线性关系的相关性逐渐变弱。
The accelerated corrosion test of recycled concrete specimens with artificial seawater was carried out,and the variation of compression strength of recycled concrete with corrosion time was studied.The results show that with the increase of fly ash content and decrease of the replacement ratio of recycled coarse aggregate,the resistance of recycled concrete to seawater erosion is enhanced,and the linear relationship between the compression strength of recycled concrete and the ratio of glue to water is better than that of recycled concrete 56d.With the extension of corrosion time,the linear relationship between compression strength and glue ratio of recycled concrete becomes weaker.
