EFFECT OF COCONUT FIBRE ASH ON THE STRENGTH OF CONCRETE

THANKGOD NNAEMEKA NWALI (NAU/2016224047)

Abstract


The urgent need to reduce excessive greenhouse emission from the manufacturing process of Ordinary Portland Cement (OPC) has led to an increasing interest in the use of agricultural waste in producing quality construction materials. This study presents an experimental investigation on the strength performance of Coconut Fibre Ash (CFA) with varying dosage. Concrete specimens were cast at 10%, 20% and 30%CFA replacement of OPC in concrete.The oxide composition of the coconut fibre ash was analyzed to determine its pozzolanic properties and also the strength performance of Coconut fibre ash based concrete specimens was evaluated by measuring the compressive strength up to 28 days. The outcome of all testproperties indicated that the mixtures prepared with 0% CFA in concrete was optimum seconded by that of 10% CFA dosage.
