The evaluation of the mechanical strengths of gum Arabic concrete (GAC) have been carried out. This was done using dosage levels of GA, 0.00 % (control) to 1.00 % as admixture, cement content of 420 kg/m3, and water-cement ratio of 0.5, to produce cement pastes and concrete specimens that were cured for 90 days in water. Results on the soundness, compressive and flexural strengths showed positive indicators for the use of GA as an admixture. An optimum dosage of 0.50 % by weight of cement was achieved. Linear regression models of Natural Log and Square Root, best described the experimental data, and parameters of interest were very significant. Response surfaces were developed showing the various levels of interactions of compressive and flexural strengths with the mix parameters.
