... and a reaction-induced part. The latter depends on the mass change of anhydrite and considers that the volumetric chemical strain rate is the sum of the solid and pore volume change. The former is given by the chemical reaction's stoichiometry and the molar volumes of anhydrite and gypsum; while the latter may...
