自发光水泥基路面材料的耐久性影响因素分析

Analysis of factors affecting durability performanceof self-luminous cement-based pavement materials

采用对照试验分析自发光水泥基路面材料,研究了发光砂和反光粉掺量两个因素对自发光水泥基路面材料的耐久性影响。结果表明,在7天的浸泡后,自发光路面材料的初始发光亮度和余辉时间下降速率最快,随着浸泡时间增多,衰减速率明显降低。40%发光砂的样本显示出最佳的抗冻和耐腐蚀性能,在固定发光砂掺量为20%时,反光粉的最佳掺量为10%。试验可为未来的材料改进和实际应用提供有价值的信息和方向。

An analysis was conducted on self-luminous cement-based pavement materials using the controlled experimental tests,and the effects of two factors of varying dosages of luminous sand and reflective powder to the durability performance of self-luminous cement pavement materials were investigated.Results indicate that after being immersed for 7 days,the self-luminous pavement material experienced the most rapid decline in initial luminous brightness and afterglow duration.However,samples immersed for longer periods showed significantly reduced decay rates compared to those immersed for 7 days.The samples containing 40%luminous sand exhibited the best frost and corrosion resistance,when the luminous sand content fixed as 20%,the optimal content of reflentive powder is 10%.This study can offer valuable insights and directions for future material enhancement and practical applications.
