Abstract
The study considered the effects of curing methods on the compressive strength of kenaf stabilised lateritic mortar at 1:5 and 1:10 cement-aggregate mix ratio. Composition of the mortar for each of the cement mix ratios was also substituted with kenaf fibres at 0, 0.5, 1.0, 1.5, 2.0 and 2.5% by weight. The effects of these factors on compressive strength of the green mortar revealed that at 1:5 cement mix, the values obtained from 28 days compressive strength of water cured samples revealed that, the kenaf replacement level should not exceed 1.0% while for air curing it should not exceed 1.5% in order to satisfy the ASTM C279 standard for O type mortar. However at 28 days the compressive strength of the samples at 1:10 cement mix did not meet the ASTM C279 standard for O and N type mortar thus indicating that binder strength was inadequate. In general the failure in kenaf fibrous mortar samples was observed to have been slow and gradual, compared to the instantaneous nature of failure observed in the pure cement-aggregate samples.
