The objective of the research was to determine the effect of saturation and ionic solutions on the elastic modulus (Young's Modulus) of rocks. It is based on the testing of 78 samples, which are considered representative of rock formations in Southern Ontario. Initially a number of physical parameters were measured, including absorption, adsorption, porosity, unit weight and length change due to freezing. A uniaxial compressive stress frame was designed and built to facilitate the stress portion of the research program. Samples were subjected to varying levels of moisture, temperature and ionic conditions for a preset time period and immediately removed and put under stress. Stress and length change of the sample were recorded during the test. Young's Modulus was calculated from the stress and strain results. All the results (combined with additional results extracted from the same samples in previous studies by Stephen Rigbey, 1980 and Ivan Dananaj, 2001) were subjected to multivariate statistical analysis, which included correlation tests, cluster analysis, factor analysis, regression and t tests.
