Abstract:To repair surface damage of piers exposed to flowing sand flushing in mountain areas,engineered cementitious com-posites(ECC)with very low water/cement ratio were researched based on the orthogonal design method by various means,including abrasion resistance test,chloride ion permeability test and microscopic test. The results indicate that the flexural strength and com-pressive strength of the repairing material are much stronger than ordinary concrete,with excellent wear-resisting performance and anti-penetrability performance,so it can be effectively applied to repair surface damage of bridge pier exposed to flowing sand flush-ing in mountain area.
