Description
Summary:The present study focuses on evaluating the axial compression characteristics of concrete, in which Manufactured Sand (M-Sand) is used as a partial and full replacement for natural sand. To retain the natural resource such as natural sand an attempt is made in this paper by partially replacing the natural sand with M-Sand. The experimental investigation involved the study of the axial compressive behaviour of RC column of grade M30 with and without M-sand. In this study the ultimate load carrying capability, the load-axial shortening, load-lateral deformation, load- strain and crack width were studied. To validate the experimental results, analytical study was also done using finite element analysis (FEM). The test results exhibits that the axial compressive behaviour of concrete column is enhanced considerably, by partial replacement of sand with 60% M-Sand for M30 grade concrete. The experimental results correlated well with the numerical results obtained from finite element analysis.
