摘　　要：随着中国高速铁路的快速发展,无砟轨道自密实混凝土在高速铁路建设中的应用越来越广泛。为了提高无砟轨道自密实混凝土的性能,粉煤灰和矿粉作为两种重要的混凝土掺合料被广泛使用。文章将对这两种掺合料在无砟轨道自密实混凝土中的应用进行对比分析,旨在为工程实践提供有益的参考。With the rapid development of China's high-speed railway,the application of ballastless track self-compacting concrete in high-speed railway construction is becoming more and more extensive.In order to improve the performance of ballastless track self-compacting concrete,fly ash and mineral powder are widely used as two important concrete admixtures.This paper will make a comparative analysis of the application of these two admixtures in ballastless track self-compacting concrete,aiming to provide a useful reference for engineering practice.
