Electrical Resistivity Testing to Rapidly Assess the Durability of UHPC-Class Materials

Ultra-high performance concrete (UHPC) is a class of cement-based composite materials with enhanced properties as compared to conventional concrete. There is growing interest, both in the United States and worldwide, in using UHPC to address needs in the bridge sector (Graybeal et al. 2020). Appropriate use of UHPC must be founded on common definitions of minimum performance attributes. As with mechanical properties, durability properties also must be defined in terms of standardized test methods. This TechBrief presents an advancement toward using electrical resistivity as a rapid method to evaluate the durability of UHPC-class materials.
