Search for: [Abstract = "Test results showed that, the geotechnical properties of RG is different to that of white gypsum. The plasticity index \(PI\) of RG was 239.6% greater due to the presence of Fe ions. Surprisingly, the electrical resistivity of both material were found to be similar. It was also noted that, although the plasticity of pure gypsum is high, the plasticity of pure gypsum was found to be short lived primarily due to instantaneous exothermic reaction between water and semihydrated gypsum."]
