Effect of Groundnut Husk Ash as fine aggregates in mortar

S Revathi, Dr.R Kumutha and Dr.K Vijai

This paper highlights the feasibility study on the utilization of groundnut husk ash as an alternative material for conventional fine aggregate (river sand). For the experimental investigation, mortar mixes were prepared by replacing conventional fine aggregate with groundnut husk ash in percentages of 0, 10, 20, 30, 40, 50 and 60.Tests were carried out to find out the compressive strength, density, water absorption and sorptivity of mortar specimens prepared by partial replacement of natural river sand using groundnut husk ash and a comparison was also made with conventional mortar specimens
