Abstract
With the increasing infrastructure across the world demand for concrete rising abnormally, to produce concrete, cement is the very vital element which binds the materials together. But primary issue arises to environment by the discharge of harmful gases like CO2, Sulphur etc… at the time of production of cement. A mineral dmixtures, a type of cementitious substance, were employed as a partial or complete replacement for cement to aid with this problem. These materials not only reduced cement usage but also improved the durability of concrete. Partial replacement of cement in concrete is an inventive and elective development material delivered by substance activity of inorganic particles. This paper is mainly focus on compressive strength of a M40 grade Ternary blended concrete made with cement and cementitious materials like Fly ash and Wollastonite. Fly ash is a industrial bi-product materials used as binder material whereas wollastonite is a naturally occurring mineral grounded to fine powder can be exploited as partial replacement to cement. The mix design has been developed for conventional concrete of M40 grade with required workability. It has been observed that the compressive strength is increased slightly and the workability is decresed with partial replacement of cement by Wollastonite in combination of flyash. The workability is decreased with increasing fly ash and wollastonite, but it is in the required range at 50% cement, 30% flyash and 20% wollastonite.
