Blended Portland cement concrete (BPCC) is a composite material composed of Portland cement mixed with supplementary cementitious materials (SCMs) such as fly ash, slag, and silica fume. These additives enhance the physical properties and sustainability of the concrete while reducing the carbon footprint associated with its production. The blend is designed to improve the performance of concrete by utilizing the synergistic effects of these materials. In severe environmental conditions—ranging from extreme temperatures and moisture levels to chemical exposure—blended Portland cement concrete provides enhanced durability and resilience compared to a traditional Portland cement concrete.
