文章针对机场道面破坏时如何能够在短时间内进行快速修复的迫切问题,采用快硬早强型特种水泥、高效外加剂和矿物掺合料,进行快硬早强自密实再生混凝土配合比优化设计和性能试验研究。室内试验和现场应用均表明,所配制的再生混凝土工作性能良好,施工方便,加水拌合后4h即可达到某新型战机起飞最低强度要求,能够满足机场道面抢修技术要求,这种混凝土也可用于公路水泥混凝土路面抢修。
In this paper, aiming at the urgent problem of how to repair the airport pavement quickly in a short period of time, this paper adopts fast hardened early strength special cement, high efficiency admixture and mineral admixture to optimize the mix proportion of fast hardened and early strength self-compacting recycled concrete Design and performance testing research. Both indoor test and field application show that the prepared recycled concrete has good working performance and convenient construction. The minimum strength requirement for takeoff of a new type of fighter jets can be reached within 4 hours after being mixed with water to meet the technical requirements of airport pavement repairs, and the concrete can also be used On the road repair of cement concrete pavement.
