The rapid increase in construction activities leads to scarcity of conventional construction materials such as cement, fine aggregate and coarse aggregate. Researchers are being conducted for finding cheaper materials. In India, there are many industries producing large amount of effluent treatment plant waste sludge which leads in problems of disposal. The final destination of effluent treatment plant sludge affects the environment. So alternative option is necessary for disposing effluent treatment sludge. In this study is subjected to the effective reuse of effluent treatment plant sludge of titanium dioxide wastes or sludge generated from Kerala Minerals and Metals Ltd (KMML). The aim of this study is to determine the strength parameters of concrete with the partial replacement of fine aggregate by waste sludge from KMML. Reuse of ETP sludge in concrete is an effective option for the problem of ultimate disposal up to greater extent. In this study the fine aggregate is replaced by the ETP sludge of Titanium dioxide with 2%,4%,6% & 8% in M25 concrete mix. The various tests such as compression, tensile and flexural strength are conducted.
