THE EFFECT OF FERROCHROME SLAG AS PARTIAL REPLACEMENT OF CEMENT IN CONCRETE

Abstract

Concrete is the second mostused material in the world after water. In 21st century, world is progressing at a breath-taking pace and rapid construction helps us to cope up with the pace. Cost of concrete and its environmental impact both depends on the constituent materials. It has become a key concern to make concrete more and more environment friendly by replacing conventional materials. Ferrochrome slag is a waste material obtained from the manufacturing of high carbon ferrochromium alloy. This slag is formed as a liquid at 1700 °C and its main components are SiO2, Al2O3 and MgO. Additionally, it consists of chrome, ferrous/ferric oxides and CaO. Ferrochrome slag has many ill effects on environments such as reduced growth of trees and animals, less reproductive capacity in mammals and also some carcinogenic diseases like Cancer. The ill effects of Ferrochrome slag can be controlled by using it in construction industry. There have been many theories proving the benefits of ferrochrome used as partial or complete replacement of Aggregates. This project aims towards the use of Ferrochrome slag (powder form) as partial cement replacement in concrete to study its effect on Compression, Tensile and Flexural Strength of Concrete.
