Abstract: The quality of concrete used in any construction work is a function of its compressive strength. In this paper, structural models are formulated to predict the compressive strength of coconut fibre-reinforced concrete mix 1:2:4 at water-cement ratios of 0.55 and 0.60 using three-dimensional elasticity equations. The results obtained using the formulated models were compared with the measured values and were found to be very close (correlation coefficient = 0.9011). For both the measured and predicted values, the compressive strength of concrete mix (1:2:4) were found to decrease as the coconut fibre contents increased.
