Barite (BARIUM) Introduction Barite is a mineral composed of barium sulfate, BaSO 4. It is usually colorless or milky white, but can be almost any color, depending on the impurities trapped in the crystals during their formation. Barite is relatively soft, measuring 3-3.5 on Moh's scale of hardness. It is unusually heavy for a non-metallic ...
In order to enhance the value of barites there is a need to explore the possibilities of using barites in the production of valuable material concrete is universal material and barite powder can be use in cement concrete. Barite (BaSO4) gets its name from its high density, in fact, barite comes from the Greek ''barys'' which means heavy.

Technology, University of Batna 2, ALGERIA. Abstract This work is devoted to the study of the possibility of valorizing uncalcined barite for the manufacture of petroleum cement, thus minimizing CO 2 emissions resulting from the decomposition of the carbonate during cooking. We propose to study the effect of adding this ore on the CRS clinker.
From this experimental study, it is observed that the use of barite coarse aggregate instead of normal aggregate in concrete leads to a significant increase in density and workability of HDC …
concrete about 18%, 67% and 25% respectively, and water absorption was reduced by 3.68% when compared to normal concrete [20-23]. Recent studies provide insight into the use of barite as a replacement for fine and coarse aggregates. However, a limited works are available on the use of barite powder as a cement substitute material.
