快硬早强水泥在道路快速修补中的应用研究

Research on the Application of Fast Hardening and Early Strength Special Cement in Rapid Road Repair

随着我国交通量的急剧增加,水泥混凝土路面会出现不同程度的损坏,若不及时进行修补,破坏情况会日益严重,造成巨大交通压力。因此,水泥混凝土路面快速修补对道路工程以及行车安全都有着重要意义。目前境内外开发的道路工程快速修补材料种类繁多,不同材料的修补原理和适用条件不同。基于此,对常用的道路工程快速修补材料进行分类,在此基础上梳理了道路修补工程对快速修补材料的技术要求,提出快硬早强型特种水泥在众多的道路快速修补材料中的优势,总结其水化机理,并结合境内外现有应用实例,探讨快硬早强型特种水泥作为道路快速修补材料存在的问题及未来发展趋势,旨在为快硬早强水泥的高效利用和深入研究提供借鉴和参考。

With the rapid increase in traffic volume in China, cement concrete pavements will experience varying degrees of damage. If not repaired in time, the damage will become more serious and cause huge traffic pressure.Therefore, the timely repair of cement concrete pavement damage is of great significance to roads and traffic safety. At present, there are many types of road rapid repair materials developed at home and abroad, and the repair principles and applicable conditions of different materials are different. Based on this, the commonly used road quick repair materials is classified in the paper, and the technical requirements for rapid repair materials in road repair projects are sorted out, the advantages of fast hardening and early strength special cement among many road quick repair materials are put forward, its hydration mechanism is concluded, and the problems of fast hardening and early strength special cement as road rapid repair materials and future development trends are discussed by combining the existing application examples at home and abroad, so as to provide reference for the efficient utilization and in-depth research of fast hardening and early-strength cements.
