Analytical Study of the Rice Hush Ash and Steel Fiber as Partial Replacement of Cement and Its Effect on Strength of Concrete

The strength of concrete depends upon the ingredients and researchers are trying for some alternative materials of cement which will not only partially replace the cement content but also improves its strength. In this research work the Rice Husk Ash (RHA) and steel fiber (SF) are used as partial replacement. The main benefit of combining the accompanying cementing material not only improves the strength but also help in preventing the pollution. The analysis has been carried out from various ratios of RHA on concrete Indicators had been added in percentage increments with proportions of 0%, 5%, 10%, 15%, 20% and 25% RHA by weight of cement in addition to that combined effect of adding various percentage of SF of 0.5%, 1% and 1.5% to obtain optimum result. The analytical study concluded that mix 10% RHA and 1.5% SF is the best combination among all mixes.
