Performance of Rice Husk Ash and Hydrated Lime Based Mortar.

Abstract

over the time, mortar has been element in building construction and its overall relevance in virtually all civil engineering practice and building construction works cannot be over emphasized. Cement being one of the major components of mortar is among the three major producers of carbon dioxide which has been acclamed to be the major greenhouse gas. the Construction industry is in search of an effective agricultural/industrial waste product that would considerably minimize the use of cement and ultimately reduce its effect on the environment. this article reports on a study carried out on the performance of rice husk (RHA) and hydrated lime (HL) based mortar. the mortar mix was prepared using , 60/40, 50/50, 40/60 for RHA/HL proportions for this research. the consistency test of the binder, specific gravity and sieve analysis of fine aggregate were determined. the compressive and tensile strength test of the mortar specimens were evaluated. the results indicates that the average compressive and strength of the mortar containing control specimen is higher as compared to those containing RHA/HL. Similarly, the compressive and tensile strength development of the mortar containing RHA/HL decreases with increase in the percentage increase of HL. However, mortar with 40/60 RHA/HL shows a relatively adequate strength and therefore considered as the optimum percentage of the binder.
