Mechanical Properties of Self Compacting Concrete with Partial Replacement of Rice Husk Ash
Journal Title: International Journal of Trend in Scientific Research and Development - Year 2017, Vol 1, Issue 4
Abstract
Self-compacting concrete (SCC) is relatively a recent development in the construction world. SCC is defined basically by two properties: Deformability and segregation resistance. It flows under its own weight while remaining homogeneous in composition. This research is aimed at examining the feasibility of using Rice Husk Ash as supplementary cementations material. In this research, the main variables are the proportion of rice husk ash (0%, 10%, 15%, 20%) and cement content.All the results were in range as per code specified. Mix 20RHA showed minimum workability.. The increase of about 25% strength at 7 days, 33% strength at 28days and 36% strength at 56 days were observed with increase of RHA content from control mix (0RHA) to 15RHA. Maximum splitting tensile strength was also obtained bythe mix 15RHA. Greatest increase in mechanical properties was observed for the mix containing 15% rice husk ash. The inclusion of rice husk ash as replacement of cement does not affect the strength properties negatively as the strength remains within limits up to 20%replacement. Inclusion of RHA showed great improvement in durability Properties of concrete.
