Structural behaviour of triple blended high-performance concrete

Abstract

After water, concrete was the material for construction that is used on the largest scale on the planet, and as an outcome of technological development, concrete's qualities have evolved over time. A study was carried out to investigate the potential use of mineral admixture as a partial replacement in high performance concrete. Since they can significantly improve concrete strength and durability properties when compared to regular Portland cement supplemental cementations materials (SCM) like Alccofine (AF) and ground granulated blast furnace slag (GGBFS) have all been used as cement replacements on a large scale over the past three decades. As a result, HPC can be produced using lower water to powder ratios by including other cementitious materials as admixtures. In this project phase, ground granulated blast furnace slag (GGBFS) and Alccofine (AF) have been employed in varied weight ratios to substitute cement to produce high strength M40 grade concrete for 7, 14, and 28 days of compressive strength (CS) as well as split tensile strength (STS) the percentages of replacement of AF of 5%, 7.5% & 10% also GGBFS percentages are 10%, 12.5 % and 15% respectively used in this project work.
