Abstract

Background: The objective is to study the strength of concrete, when using definite proportions of materials generated from industrial wastes with micro particles. As per Integrated National Plan on waste, ceramic wastes are considered as nonhazardous. Methods/Analysis: In the present work, partial replacement of concrete compositions with Titanium dioxide TiO2 micro particle, ceramic wastes and rice husk ash are analysed. The coarse aggregate is replaced by 30% of ceramic waste and cement has been replaced by 10% RHA with added TiO2 micro particle in the range of 0.5%, 1%, 1.5% and 2% by weight for M30 grade concrete. Findings: Concrete specimens are tested and compared in terms of compressive, split tensile values to the conventional concrete. These tests were carried out to evaluate the strength for 7 and 28 days. Test results have indicated that the strength achieved by replacing coarse aggregate with 30% ceramic waste and cement with (10% of RHA+ 1% of TiO2 ) is in optimum condition without affecting properties of fresh and hardened concrete. Applications/ Improvements: Combination of nanotechnology with use of industrial waste results in attaining an energy efficient and greener concrete. Also an industrial waste in concrete not only helps in their disposal, but also saves the natural resources.
