Scheffe’s and Osadebe’s modeling techniques were used in formulating two mathematical
models for the prediction of compressive strength of sand laterite blocks. The models were tested
for adequacy using statistical tools. Comparative analyses were made on the results of
predictions from the two models. The student’s t-test statistics proved that there is no significant
difference between the predicted results of the two models at an α-level of 0.5. The percentage
difference between the two model results ranges from a minimum of 0.25% to a maximum of
6.66% which is also insignificant. These comparisons show that both models are adequate and
any of them can be used for prediction of the compressive strength of sand -laterite blocks given
the mix ratios or vice versa.
