Experimental research on mechanical properties of ultra-high performance concrete with coarse aggregate
Adding coarse aggregates to ultra-high performance concrete(UHPC)is to significantly reduce production costs and make it more easily accepted by the market while achieving better mechanical properties.This paper adjusts the factors such as slurry to bone ratio,sand ratio,coarse aggregate type,and water reducing agent type in the UHPC-CA mix proportion.By comparing the compressive strength at different ages,further analysis is conducted from a microscopic perspective to explore the influence of various factors on the mechanical properties of UHPC-CA.
