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 specific gravity (SG) test can easily distinguish these gems. Calcite has a higher SG range (2.71-2.94) than gypsum (2.30-2.33). Synthetics. Gypsum has a myriad practical uses and a long history of industrial applications. Despite its abundance, gypsum is also widely synthesized — as an industrial by-product — for many purposes.
These test methods cover the physical testing of gypsum, gypsum plasters, and gypsum concrete. The values regarded as the standard are either in inch-pound units or SI (metric). The values stated first shall be regarded as the standard. Values following in parentheses are approximate and are provided for information purposes only.
