Abstract

This study investigates the effect of using Guinea Corn Husk Ash (GCHA) as partial replacement for cement in mortar production. Guinea corn husk ash(GCHA) was incorporated into the mix in various proportions for cement replacement at 0%, 2%, 4%, 6%, 8% and 10%. A total of seventy-two cubes were cast in a mould of size: 0.1m x 0.1m x 0.1m, and then cured in water. The Slump test was carried out on fresh mortar in accordance with BS EN 12350-2 (2009). The hardened specimens were tested for compressive strength at 0, 3, 7, and 28 days and water absorption test in accordance with BS EN 12350-2 (2009)and BS 1881-122 (2011) respectively. The results showed that the compressive strength of the mortar increases up to 4% replacement level before it begins to decrease with an increase in GCHA replacement. There is a significant increase in mortar strength at all percentage replacement levels as the curing age increases. The compressive strength of mortar with 4% GCHA yielded the highest value of compressive strength at 28 days. The research has also shown an increase in slump and water absorption of mortar as the percentage of GCHA increases. To achieve optimum strength of mortar incorporating GCHA, it is concluded that the percentage replacement should not exceed 4% replacement of cement.
