Strength and durability properties of quaternary blended high strength concrete
Concrete is in great demand due to global infrastructure expansion. Cement is a critical component in the production of concrete because it binds the ingredients together. But the primary issue arises in the environment due to the release of toxic gases such as CO3 and sulphur into the atmosphere. To overcome this, some other cementitious materials, namely admixtures, were utilized as partial replacements for the cement. In this study, concrete was made for M70 grade with a quaternary blend in composition with cement, silica fume, metakaolin, and alccofine. Silica fume is largely used as a mineral admixture in high-strength and high-performance concrete. Metakaolin is a cementitious material developed from the heat treatment of natural kaolin deposits. Alccofine is a new type of admixture in concrete. These materials not only lower the consumption of cement but also help concrete maintain its qualities, so it is proposed to study the mechanical, and durability properties of hardened concrete. This paper mainly highlights on the utilization of metakaolin, Alccofine and silica fume as they replaced the cement in varying proportions to get the required strength of M70 grade concrete for 7 days of compressive, and split tensile strength.
