Bearing in mind the increasing worldwide availability of pulverised fly ash (PFA) and rapidly decreasing source of natural and other good quality aggregates, fly ash can be used to produce aggregates (sometimes fly ash will be added to concrete as a fine aggregate). Use of fly ash not only reduces the problems created by it but is also beneficial in many other aspects. Today it is used as mineral admixture and acts as partial substitute for cement. Although the raw materials required for production of cement are generally available in almost all parts of world, Portland cement requires relatively costly materials in terms of energy expanded in its production. It is estimated that total energy consumed, including fuel cost, is about 7500 MJ/Tone for ordinary Portland cement where as it is only 150 to 400 MJ/Tones for fly ash. So use of PFA results in major savings of energy and raw materials. Replacement of each tone of cement saves at least 6000 MJ of energy, which is equivalent to a barrel of oil or a quartertone of coal. Use of fly ash also helps in preservation and protection of environment, which is an issue of paramount importance to the Faster construction, it is necessary to have higher early strengths for Faster removal of form works, which intern requires higher cementations content of 350 to 550 Kg/m3..The objective of this study is to optimize the Steel Fiber Reinforced Self Compacted Concrete (SFRSCC) in the fresh and in hardened state. But the references indicate that some studies are available on plain SCC but sufficient literature is not available on SFRSCC with different steel fibers & different aspect ratio.Steel Fiber-reinforced self-compacting concrete (SFRSCC) is a new type of concrete mix that can mitigate two opposing weaknesses poor workability in fiber-reinforced concrete and cracking resistance in plain SCC concrete.
