Krithika Assistant Professor (O.G), Civil Engineering Department, SRM University, Kattankulathur, Chennai, India ABSTRACT The use of marble in various ways is increasing every year worldwide due to increase in population. Due to increasing usage, there is increase in waste product of marble which creates lot of problem in disposal. And hence as a recycling act of this waste product, a lot of research work has been done in improving the performance of concrete with partial replacement of cement, fine aggregate and coarse aggregate. Ultra fine sludge is obtained as waste product during the process of cutting, polishing of marble in marble industry. This sludge does not possess any binding property but it act as filler material in the concrete. Thus, this material will fill the voids in concrete which in turn increase the density and strength will also be more than the conventional concrete. The normal cement concrete of M40 grade was taken into account and the cement was replaced with ultra fine sludge in different ratios of 5%, 10% and 15%. The properties like compressive, split tensile, flexural strength and durability properties were determined in this paper. 5% of ultra fine sludge is optimum replacement for the mechanical properties. Key words: Ultra fine sludge concrete, Cement, Marble waste, Compression, Split tensile, Flexural. Cite this Article: Manda Goutam V Sai Manikanta and P.

INTRODUCTION In present scenario, concrete technology is varying and developing. So cement scarcity is becoming more and at the same time pollution is created from the cement industries. In the same way marble usage is also more and marble waste is creating pollution. Presently large amount of marble waste is produced from the marble industry. This waste may create
