Ultra-high performance concrete with coarse aggregate(coarse aggregate UHPC)can take into account both ultra-high strength and ultra-high durability performance,and further reduce shrinkage,but the problem of large self-shrinkage has not been solved.This article mainly studied the effects of superabsorbent polymer(SAP)on the workability,autogenous shrinkage and mechanical properties of CA-UHPC compared to expansion agents at 0.1％,0.15％,and 0.2％of cementitious material masses.
