Microstructural investigation of ternary blended high-performance concrete using supplementary cementitious materials

An experimental study was performed to understand the behaviour of cementitious material on the fresh and mechanical properties of ternary blended high-performance concrete (HPC). Ordinary Portland cement (OPC) was replaced by various proportions of micro silica (MS) and fly ash (FA) resulting in ternary concrete mixes forming additional cementitious compounds that contribute to the strength and durability of the concrete. Various phases present in the cementitious materials used in the mix were observed using X-ray diffractogram. On comparing to the HPC made only with OPC, utilization of 10
