Abstract
Concrete is a widely used construction material. It must be designed to withstand severe environment before taking most of the inspirational forms. The Engineers are now-a-days try to improve the its capacity with different ideas.. Like adding various admixtures and supplementary cementitious materials. The main objective of the SCM is capacity which that replace the cement and provides cementitious property then it decreases the price of the Portland cement. The material which can be used as supplementary cementitious material such as fly ash, GGBS, steel slag, silica fume. In these modern days most of concrete produced from these materials. To optimize concrete mixtures the properties of the materials compared with each other. The silica fume is a mostly used supplementary cementitious material, which increase the durability and for the design of high strength concrete. From steel manufacturing industries steel slag byproducts are produced 3. The steel slag which is used as aggregate in concrete for hot mix surface application purpose. The workability industrial byproduct there is a need of extra work for the replacement of fine and coarse aggregate with steel slag for purpose of the considerable benefits 5. The presence of free lime and Magnesium oxides in steel slag has a property of expanding nature , because this phenomenon steel slag are not used as aggregate in manufacturing of the concrete. Suitable treatments of weathering and usage of Pozzolanic materials like silica fume with steel slag is decrease the expansion of the concrete. Some small faults in material hence it is achieved by proper combination of materials each other, then it can be produce a good product with increases the total quality of the material and enhance the various properties.
