ABSTRACT In the present situation the scarcity of natural sand has become a problem for the construction industry, after much research the developed technology gave rise to new generation sand named as M-sand or Manufacture sand. The M- sand is produced by crushing rocks and stones to sizes and shape similar to N-sand or Natural sand. In the present study an effort has been made to investigate the potential usage of M-sand in SCC. Self-Compacting Concrete (SCC) is an innovative concrete that does not require vibration for placing and compaction. It is able to flow under its own weight, completely filling formwork and achieving full compaction, even in the presence of congested reinforcement. In the work, an attempt has been made to make a comparative study on the fresh and hardened state properties of M35 self-compacting concrete with the replacement of River sand by manufactured sand. This paper presents an Experimental Investigation on Strength aspects like Compressive and Split Tensile Strength of Self Compacting Concrete and Workability tests (Slump, L-box, U-box, V-Funnel and T50) are carried out. The methodology adopted is that manufactured sand is replaced by 0%, 25%, 50%, 75% and 100% in natural sand and performance is measured. Keywords: M-Sand- Manufacture Sand, SCC- Self Compacting Concrete, N-sand- Natural Sand I. INTRODUCTION The development of new technology in the material science is progressing rapidly. In last three decades, a lot of research was carried out throughout globe to improve the performance of concrete in terms of strength and durability qualities. Consequently concrete has no longer remained a construction material consisting of cement, aggregate, and water only, but has becomes an engineered custom tailored material with several new constituents to meet the specific needs of construction industry. The growing use of concrete in special architectural configurations and concrete in special architectural configurations and closely spaced reinforcing bars have made it very important to produce concrete that ensures proper filling ability, good structural performance and adequate durability. In recent years, a lot of research was carried out throughout the world to improve the performance of concrete in terms of its most important properties, i.e. Strength and durability. Concrete technology has under gone from macro to micro level study in the enhancement of strength and durability properties from 1980’s onwards. Till 1980 the research study was focused only to flow ability of concrete, so as to enhance the strength however durability did not draw lot of attention of the concrete technologists. This type of study has resulted in the development of self- compacting concrete (SCC), a much needed revolution in concrete industry. Self-compacting concrete is highly engineered concrete with much higher fluidity without segregation and is capable of filling every corner of form work under its self-weight only (Okamura 1997). Thus SCC eliminates the needs of vibration either
