A Comprehensive Review Of The Response Of Ultra-High Performance Concrete (UHPC) To Blast Loads

Abstract

This study investigates the performance of Ultra-High Performance Concrete (UHPC) and Reactive Powder Concrete (RPC) under blast loading conditions, comparing them to Normal Strength Concrete (NSC). Controlled blast tests using ANFO explosives demonstrated that UHPC and RPC slabs exhibit significantly better blast resistance than NSC, with lower deflections and more durable crack patterns. While NSC slabs experienced substantial deformation and damage, UHPC and RPC slabs showed reduced maximum deflection, with RPC particularly benefiting from fiber-bridging effects. These findings highlight the potential of UHPC and RPC as superior materials for both new constructions and retrofitting applications, offering enhanced protection against blast events. However, the study also acknowledges challenges in accurately simulating real-world blast conditions, as well as the influence of variations in material composition, manufacturing, and curing processes on performance. Future research should focus on refining blast resistance testing methodologies and exploring the long-term durability of UHPC and RPC under diverse conditions.
