This study investigates the effect of the chemical environment on the mechanical characteristics of pulverized kenaf fibrous fuel ash concrete with a volume percent of 0.75, with a particular emphasis placed on the consequence of acidic, alkaline and sulfate solutions. The study also explores the effect of compressive and flexural characteristics of composites and a considerable reduction in each strength was seen; nevertheless, kenaf composites exhibited greater strength stability. The weakening of the fibre/matrix interface caused by environmental factors are identified using scanning electron microscopy (VPSEM). The increase in mechanical performance over a prolonged period when exposed to various of environments was attributed to the addition of 25% fly ash. © 2024, Construction Research Institute of Malaysia.
