Rehology Behaviour and Mechanical Properties of Fly Ash Contened Self Compacting Concrete

Early SCC relied on very high contents of cementitious paste, the mixes required particular and well-controlled placing methods to avoid segregation, but the high contents of cement paste made them susceptible to shrinkage and high heat generation. The overall costs were very high and applications therefore remained very limited. After series of progressions it is no longer a material consisting of cement, aggregates, water and admixtures. Now a day SCC is a hot topic in the industry and that there are possibilities of using it for a wide variety of purposes.

Self-Compacting Concrete is considered to be the most hopeful building material for the expected revolutionary changes on the job site as well as on the desk of designer civil engineers. Self-compacting concrete consists basically of same components as normal vibrated concrete except that excess of the finer material as water reducing agent, is used. SCC has excellent deformability, high resistance to segregation and can filled in heavily reinforced section without applying any vibration. This paper presents a brief review note on the state-of-the-art of self-compacting concrete using waste material, future sustainability and an eco-environment friendly concrete.
