Abstract
Ultra High Performance Concrete(UHPC) is a construction material that has a low water-binder ratio (W/B), a high-performance chemical admixture(SP), mixing material and steel fiber, and performance superior to that of regular concrete in terms of liquidity and strength. In the study, UHPC was used to prepare construction external panels that can replace existing stone panels. In addition, experiments were conducted to access the effects of differences in chemical admixture input amount, the number of fillers, antifoaming agent and steel fiber. An evaluation, was conducted, such of concrete compressive strength, flexural strength, impact strength, absorption rate, and frost resistance. The results showed compressive strength up to 115.5MPa, flexural strength of 20.3MPa, and an absorption rate of 1%. In this case, impact strength and frost resistance evaluation were satisfied with outward observed.
