SOME STUDIES ON REUSE OF INDUSTRIAL WASTESP. CHANDAN KUMAR, M. MURALI, M. POTHARAJU AND P. MALIESWARAAbstract Disposal of industrial solid wastes has emerged as major environmental problem. The suitability and demand for usage of different industrial wastes like flyash, slag etc. in favoured to conserve the natural resources base and reduction in consumption of naturals materials in construction to attain sustainable development. In the present investigation, an attempt has be made to study the improvement of strength and durability of concrete by using industrial waste (Flyash). The present study focuses on the durability characteristics of M20 grade concrete with partial replacement of fly ash 00/0, 250/0, 35% and 45% in cement for this 100 x 100 x 100 mm cubes were cast and immersed in the Sulphuric acid solution of 0.1, 1 and 3 percentages of concentration. The reduction in strengths and weight has been found at intervals of 3 days up to 28 days. The final characteristic strength results shows beneficial effects of increase in durability with higher percentage of fly ash repayment compared to normal concrete when exposed to various concentrations of acid. Use of flyash observed, to have a significant impact is strength and durability of concrete when the flyash is available locally in large quantities.
