Treatment of Clay with Oil Palm Fibre Ash and Rice Husk Ash Mixture for Burnt Clay Bricks Production

The current study examines the use of oil palm fibre ash (OPFA) and rice husk (RHA) mixture in treatment A-6 Makurdi clay for burnt brick production. results show that compressive strength 9.4 MN/m2 untreated increased to 10.86 2%OPFA+2%RHA treated brick. corresponding water absorption 14.9% 16.2% value is greater than 10.3 MN/m^2 which minimum negligible weather (NW) conditions. less 17%, 22% ‘no limit’ are maximum values severe (SW), moderate (MW) NW respectively. Based on combined criteria, bricks production with adequate as a load-bearing wall areas condition.
