Freeze-Thaw, Surface Resistivity, and High Temperature Performance of Local UHPC

Ultra-High Performance Concrete (UHPC) is an important material for modern structures, due to its high strength properties in regards to tension, compression and ductility. UHPC is well known to distinctly surpass common-use concrete in strength, but its relation to this concrete in durability is less documented. The intent of this paper was to develop a UHPC mixture sufficient for various climates, and compare its durability capacity to a normal-strength concrete mixture. Strength and durability related to weathering and surface resistance were considered, as well as material properties, to effectively withstand plausible environmental conditions. These parameters were then compared to the values of normal-strength concrete. The experimental results show that while UHPC possesses acceptable durability in most categories, it lacks exceptionable durability when simply meeting the design regulations. The findings can be used to further define UHPC, and improve the standards relating to it.
