Ultrahighperformance concrete (UHPC), also known as reactive powder concrete, is a new cementitious composite characterized by excellent mechanical properties and durability performance [3,4,5]. However, UHPC is also characterized by a low water to binder (w/b) ratio that can cause a low degree of cement hydration, specifically less than 50%.
