Influence of curing regime and steel fibres on the mechanical propertiesn of UHPC

摘要

The effect of accelerated curing and steel fibre volume on ultra-high performance concrete (UHPC) is the focus of this paper. The compressive strength and microstructural properties of UHPC were evaluated under water, steam and heat curing. The results show that heat-cured samples have higher mechanical properties than those undergoing the other curing techniques. Experimental studies were conducted on heat-treated specimens with different steel fibre volumes and aspect ratios (2.5% and 2.0% of
