Abstract

Concrete, a homogeneous mixture of cement, fine aggregate, coarse aggregate and water is widely been used in construction activities. But cement and fine aggregate are becoming consequently costlier and their demand also increases every day. There is a push towards sustainability in recent times in the construction industry. As large scale production of cement causes emission of greenhouse gases and depletion of natural resources and also natural sand of good quality are becoming scarcer and costlier due to non-accessibility of river during entire year, illegal dredging, rapid growth of construction activities etc. So it is necessary to search an alternative material to use as cement and natural sand in construction activities. The use of silica fume as a partial replacement of cement is an effective method of pollution reduction and conservation of resources, since it reduces cement use. In addition, silica fume is used in combination with copper slag to make concrete structures more durable. The present work is directed towards developing a better understanding on strengths characteristics of concrete using as a partial replacement of cement by silica fume and fine aggregate by copper slag. The Dissertation work is carried out with M20 grade concrete and tests were conducted. Concrete mixtures were evaluated for workability, compressive strength and split tensile strength.
