Abstract

Type of column that incorporates two materials or elements of design in its structure is a composite column. In engineering, a composite column may also be understood to mean a column of concrete reinforced by a steel core. The latter type of composite column is often used in construction due to its structural advantages, including corrosion protection and increased strength. These structures are intended to be load-bearing and have many advantages over plain steel or concrete .The steel backbone of a composite column lends increased strength and resistance to buckling. Since steel is lighter than concrete but also stronger, the necessary support structures are smaller and more lightweight than they would be if only concrete were being used. These advantages make composite columns an efficient and economical solution for large-scale construction projects. Use of Metakaolin and silica fume as partial replacement of cement in concrete for strength and economy. The proper dispersion of cement, Metakaolin and Silicafume in the concrete and composite column plays an important role in this study. The experimentation is performed for different water cement ratio of 0.35 to 0.5% for in composite column of Square and Circular Section. Then the specimens are to be tested on 7thday, 14thday, 28th day
