A total of 24 concrete samples of nominal dimensions 300mm x 150mm x 100mm each were produced for laboratory testing using six cement dosages of 150 Kg/m3, 200 Kg/m3, 250 Kg/m3, 300 Kg/m3, 350, and 400 Kg/m3. Samples were buried at a swampy area with a moisture content of 67.38% for 56days, 84days, 112days and 196days. For concrete dosed at 400 Kg/m3, compressive strengths of 20.8MPa, 19MPa, 16.5MPa, and 12.7MPa were recorded for 56days, 84days, 112days, and 196days, respectively. The modulus of elasticity for the concrete dosed at 400 Kg/m3 is 29741.38 MPa, and the Poisson ratio is 0.177. The bulk modulus for concrete dosed at 400 Kg/m3 was found to be 15346.43MPa and the shear modulus was 12634.4 MPa. Concrete dosed at 150Kg/m3 recorded a Von Mises stress of 15.407MPa, while concrete dosed at 400 Kg/m3 recorded a higher von Mises stress of 21.984 MPa. The Von Mises stresses were far greater than most of the average uni-axial failure stresses. The maximum distortion energy for concrete dosed at 150 Kg/m3 is 9.028 KJ/m3, while that dosed at 400 Kg/m3 has a distortion energy of 6.067 KJ/m3. Other mechanical properties such as the strains, principal stresses, and failure angles were also assessed. The general trend of the analyses revealed that prolonged exposure of concrete to a humid environment has an adverse effect on the engineering performance of concrete.
