WebApr 2, 2024 · Reactive powder concretes (RPCs) are defined as high ductility and ultra-high-strength cementitious composites with enhanced physical and mechanical features . They are unique concretes that are enhanced by microstructures via correct gradients of all substances in the mixes to generate maximum density . Ultra-High Performance Concrete (UHPC), is also known as reactive powder concrete (RPC). The material is typically formulated by combining portland cement, supplementary cementitious materials, reactive powders, limestone and or quartz flour, fine sand, high-range water reducers, and water.
