It has a mixer of coarse aggregate, fine aggregate, cement and water. We have used the admixtures for some changing the properties of cement. To the continue hydration, the relative moisture inside the concrete should be 85% for this curing to be continue. Curing is supply of water or by steam from outside (External Curing) or from inside (with help of any moisture containing agent i.e. Self-Curing). In this study, we study the review of previously published papers on self- curing concrete and find out suitable moisture containing agents and some another Admixtures to improve moisture holding capacity of concrete. The effect of self-curing concrete of compressive and split tensile strength is also study. Key words: Compressive strength, Split tensile strength, Steel fibers, Self-curing concrete, Pre-saturated dust, curing, PVA, PEG-400, Alccofine CHAPTER-1. ________________________________________________________________________________________________________ INTRODUCTION 1.1 SCOPE OF RESEARCH Concrete is the most consumed construction material for buildings at present. The achievement of designed strength and durability of concrete relies largely on sufficient compaction during placement. Inadequate compaction can dramatically lower the performance of mature concrete in- situ. Therefore, to ensure adequate compaction and homogeneity of the cast concrete and to facilitate its placement especially in structures with congested reinforcement and restricted areas, self-compacting concrete has been introduced. It all started around 1988 at Tokyo University when Okamura et al. (1998) established the basic description of SCC. The history of self-compacting concrete (SCC) dates back to late 1980s. SCC
