Thus the main requirements of SCC are flow ability, filling ability; self compacting without segregation .it can be achieved by proper mix design, which can be more appropriate stated as proportioning of various compacting of the concrete. Due to industrialization there is huge amount of rice husk ash and ground granulated blast furnace slag created. Both are cheaper and easily available can be use as admixture in self compacting concrete. Keywords: Rice Husk Ash, GGBS (Ground Granulated Blast Furnace Slag) I. INTRODUCTION More than hundred papers are reviewed and presented in the main thesis, out of which few important reports have been presented. Self compacting concrete was developed at first in Japan by Prof.Okamura [6] of Kochi university of Technology in 1986. Studies to develop SCC and its workability have been carried out by Ozawa & Maekawa at the University of Tokyo. Research scholars all over the globe have reported the need of admixtures in SCC. H.Okamura & M. Ouchi (1997) [7] have investigated the effect of superplasticiser on the balance between flowability and viscosity of mortar in SCC. K.Ganesh Babu and V. Sree Rama Kumar (2000) [ 3] quantified the 28-day cementitious efficiency of ground granulated blast furnace slag (GGBS) in concrete at the various replacement levels. Nan Su et al (2001) [5], Okamura H (2003) [6] and EFNARC guidelines (2002 & 2005)[11] have proposed the mix design methods for SCC using different mineral admixtures. Many investigators have reported the use of fly ash, GGBS etc. as filler materials in SCC. Suresh Babu. T (2009)[10] has studied elaborately about stress-strain behavior of SCC and GFRCC with different admixtures. Mehta P.K (1977)[4], Seshagiri Rao M.V (1999)[12], Rama Rao G.V (2004)[9] have reported the effective use of RHA as an admixture to improve the strength characteristics. Papworth (1994) [8], D.R. Seshu (2003)[2] have presented models for the stress- strain behaviour of conventional, fibre reinforced and steel fibre reinforced self compacting concrete mixes respectively. Annie Peter (2007)[1] have reported the flexural behaviour of steel fiber reinforced SCC. II. EXPERIMENTAL PROGRAMME In order to achieve the fresh and hardened properties of self compacting, numbers of cubes, cylinders and beam were casted with three different mixes of M30, M40, and M60. The cement, sand and coarse aggregates were weighed according to the mix proportion as per EFNARC Guideline. To this dry mix the required quantity of GGBS (Alccofine1206) and RHA was added and homogenously mixed. The viscosity modifying agent (VMA) was added at the rate of cementations material. Cement: Ordinary Portland cement of 43 grades from single lot was used in this investigation. It was fresh and without lumps. All tests on cement were conducted, as per procedure laid down in code IS: 8112-1989 Fine Aggregates The sand used for the experimental programmed was locally procured and confirmed to Indian standard IS: 383-1970. Properties of the fine aggregate used in the experimental work. The aggregates were sieved through a set of sieves to obtain sieve analysis. The fine aggregates belonged to grading zone II. Coarse aggregates Two types of aggregate with different sizes have been used in this study. CA - I aggregate passing 20 mm sieve and retained on 12 sieves, CA - II Aggregate passing 10 mm sieve and retained on 6mm The percentage contributions of aggregates have been taken as 50% CA - I and 50% CA - II for proportioning of the concrete mix. The aggregates were washed to remove dust and dirt and were dried to surface dry condition. The aggregates were tested as per IS: 383-1970 Ground Granulated blast Furnace slag Ground granulated blast furnace slag (GGBS) is a byproduct from the blast furnace used to make iron. These operate at a temperature of about 1500 degrees centigrade and are fed with a carefully controlled mixture of iron-ore, coke and limestone. ALCCOFINE 1206 is a specially processed product based on slag of high glass content with high reactivity obtained through the process of controlled granulation are used in this investigation. The raw materials are composed primary of low calcium silicates.
