Abstract

This study represents the behaviour of concrete, having partial replacement of cement with barites. The focus of our project will be strengthening concrete by replacing cement by barites in the most economical way by using the proper grade of concrete for increasing density of concrete. The mineral barite is a cheap and locally available material. Barites is a clean, smooth, naturally unresponsive and inexpensive mineral. It is non-toxic and also chemically and physically uncreative. It is used to make high-density concrete to block xray emissions in hospitals, power plants and laboratories. They can help to improve the workability and reduces the heat of hydration. M20 grade concrete was used for which the barites are replaced and an experimental study was carried out and the effect on compressive strength characteristics (0%, 10%, 20% and 30%) was studied. Water-cement ratio is to be kept same as that of normal concrete. The compressive strength of the concrete mixtures has been obtained at 7, 14, 28 and 56 days. The result of the laboratory work showed that replacement of cement with barites increases, up to 10% for compressive strength of concrete.
