In this study, the mechanical properties and permeability variation in single joint rock samples filled with a gypsum layer were investigated. In order to simulate the inclined infilled joint, the solid cylinders were saw-cut at the dip angles of 90°, 60°, 45°, 30° or 0° with respect to the samples' axes, and then joined together with gypsum. Triaxial …
Gypsum steps in as a cooling agent, curbing the heat of hydration. Strength Boost: Gypsum-infused cements boast superior strength and hardness compared to their non-gypsum counterparts.
