Manikandan1, Dr. T. Felixkala2 1 Research Scholar, Department of Civil Engineering, St. Peter’s University, Chennai, India 2 Professor and Head, Department of Civil Engineering, Dr. M.G.R. Educational and Research Institute University, Chennai, India ABSTRACT – This study focused on the Structural behavior of Self – compacting concrete (SCC) is a fluid mixture, which is Self compacting High Performance Reinforced concrete beam. suitable for placing difficult conditions and also in congested Granite waste is obtained as a byproduct during sawing, shaping, reinforcement, without vibration. The study of granite powder and cutting of granite and it was characterized from a chemical and physical point of view in order to use in mortar and concrete, especially for self-compacting mixtures. The study of a raw material is abundantly available as a waste in industries, it as fine aggregate and partial replacement of sand with admixtures in the production of self compacting concrete beam.1 Self-Compacting concrete offers many benefits to the can be considered to replace as fine aggregate, especially to construction practices i.e., the elimination of the compaction replace sand. The effect of using granite powder and granules as work results in reduced costs of placement, shortening of the constituents of fines in mortar or concrete by partially reducing construction time and therefore improved productivity. The quantities of cement as well as other conventional fines in self global consumption of natural river sand is very high due to compacting concrete. This project emphasizes on the use of the extensive use in concrete.2 The demand for natural river granite waste as substituent to Fine Aggregate (cc and GP sand in developed countries is particularly high for its 25%).In order to increase the strength the margin by replacing cement with 7.5% silica fume, 10% fly ash, 10% blast furnace slag, and 1% super-plasticizer. Data presented include the Load at Failure and Deflection of the Self compacting High infrastructural development purposes. Granite waste is obtained as a byproduct during sawing, shaping, and cutting of granite and it was characterized from a chemical and Performance Reinforced concrete beam. When test was physical point of view in order to use in mortar and concrete, conducted at 7days, 14 day and 28 days, the test results were especially for self-compacting mixtures. In this study, a raw compared between control concrete (C.C) and Granite powder material is abundantly available as a waste in industries, it can 25%. be considered to replace as fine aggregate, especially to Keywords – Granite powder, Admixtures, Load at Failure and Deflection and Self compacting High Performance Reinforced replace sand.3 This includes deformability, passing ability, filling capacity and segregation resistance. In India granite stone industry currently produces around 17.8 million tones of concrete Beam (SCHPRCB). solid granite waste, out of which 12.2 million tones are rejected at the industrial sites, 5.2 million tones as the form of I. INTRODUCTION cuttings/trimmings or 0.4million tones granite slurry are at processing and polishing units. E-ISSN :2348 – 8352 www.internationaljournalssrg.org Page 8 International Conference on Current Research in Engineering Science and Technology (ICCREST-2016) One way to reduce the intensive labor demand for vibration of highly congested sections is to use Self compacting concrete.

SCC invariably incorporates chemical admixtures per code IS 10262:2009 and given Table 1. - in particular, a high range water reducing admixture Table 01: Mix design for M60 grade of SCC (HRWRA) and sometimes, viscosity-modifying agent (VMA). 7 concrete.
