The Engineering Assessment of Locally Produced Rice Husk Ash as Cement Partial Replacement in Concrete

Engr. Samaila Muazu Bawa


Abstract

The purpose of this study is to look into the strength contributions of rice husk ash derived from three different species of locally grown rice. The three varieties used are known locally as Jan-Nera, Yar-Yarima, and Jamila, and they differ in texture, yield, and post-harvest behavior. The compressive strength and setting time of concrete with percentages of cement replacement of 0%, 5%, 10%, and 15% for the various rice husk ash were investigated at a constant water to binder (w/b) ratio of 0.6.  It is clear that the ashes for all three types of locally produced rice show strength enhancement (28 days) at 5% and 10% but decline at 15%, with Jamila showing strength enhancement throughout the replacement levels. Additional chemical analysis is required to fully understand the actual behaviors of these rice husk ashes in order to cover all of the properties required for concrete soundness in terms of strength and durability.
