摘要
再生混凝土作为新型环保、可持续发展材料,已经受到广泛的关注与重视。将再生混凝土作为道路材料,其耐久性的好坏直接影响混凝土路面的使用寿命。通过研读国内外相关文献,对比与分析了再生混凝土耐久性(主要包括抗冻性、抗渗性、抗碳化以及耐磨性等)的主要影响因素,并总结出,通过降低水灰比、掺入外加剂和掺合料、控制再生骨料掺合量、改善施工工艺、使用改性骨料等措施,可以有效提高再生混凝土的耐久性,旨在对再生混凝土耐久性的深入研究与工程应用提供依据。
Recycled concrete,as a new type of environmentally friendly and sustainable development material,has received widespread concern and attention.Recycled concrete is used as road material,and its durability directly affects the service life of concrete pavement.By studying the relevant literature,the main factors affecting the durability of recycled concrete were compared and analyzed,including frost resistance,permeation resistance,carbonation resistance and abrasion resistance.It was concluded that measures such as reducing the water-cement ratio,incorporating additives and admixtures,controlling the amount of recycled aggregate,improving the construction process,and using modified aggregates could effectively improve the durability of recycled concrete.In-depth research and engineering application of recycled concrete durability are provided the basis.
