Study of the Properties of Concrete by Partial Replacement of Pozzolana Portland Cement by Ultra Fine Slag

Abstract

1. GENERAL As we know India is a developing country and developing country’s growth mainly depends on how well it uses its natural resources as well as their byproducts. Ultrafine Ground Granulated Blast Furnace Slag (UFGGBS), a waste product obtained from steel industries, complies with Indian standards for use in cement and concrete. Due to its better shape and particle-size distributions and the dispersing property, ultrafine slag adds good workability and cohesiveness to cement and acts like a chemical admixture. Also apart from being economic, ultrafine slag imparts great strength to concrete. Slag is a known product and people have been using it for ages. It was recently used in construction of the tallest concrete structure in the world, Burj Khalifa. In India, many structures have also been constructed, including the bandra outfall project and its tunnel lining projects. By finding the optimum content of slag percentage to be replaced by the cement, we can achieve a high performance, high strength concrete and also make the construction economic.
