Abstract. These test methods cover the physical testing of gypsum, gypsum plasters, and gypsum concrete. Test methods are detailed for the following: precautions for physical tests, reagents and materials, free water, fineness, normal consistency of gypsum plaster and gypsum concrete, setting time, setting time (temperature rise method), compressive strength, and density.
A certain period is required after the mixing procedure to raise the consistency up to a desired level for easier productivity. A standard setting time if essential because if the gypsum sets too fast then a considerable amount of gypsum will be ... Initially the volume of gypsum plaster contracts during the casting process. When the setting is ...
