Study on the partial replacement of fine aggregate using

The aggregates are of two kinds, coarse aggregate such as crushed limestone or granite and fine aggregate such as river sand or manufactured sand. Various chemical admixtures can also be added to achieve varied properties. Water is mixed in concrete so that the concrete gets its shape and then gets hardened through a process called hydration.
