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.
