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.
The purpose of this work is to study five physical properties (water/powder ratio, setting time, fineness, porosity and density) and compressive strength for local juss and technical plaster; to make a comparison of these properties between the two types of gypsum products and to find the relationships between these properties. DEFINITIONS
Gypsum is a soft sulfate mineral composed of calcium sulfate dihydrate, with the chemical formula CaSO 4 ·2H 2 O. It is widely mined and is used as a fertilizer and as the main constituent in many forms of plaster, blackboard/sidewalk chalk, and massive finegrained white or lightly tinted variety of gypsum, called alabaster, has been used for sculpture by many cultures including ...

In the present study, the rheology test was used to determine the influence of gypsum fineness in the first few hours of cement hydration. The analysis of the hydration and rheological behaviour of cement pastes with the addition of fine, medium, and coarse gypsum made it possible to measure the influence of gypsum fineness on the cement paste. 2.

Gypsum is calcium sulfate (CaSO4). Refined gypsum in the anhydrite form (no water) is percent calcium (Ca) and percent sulfur (S). Usually, gypsum has water associated in the molecular structure (CaSO4·2H2O) and is approximately percent Ca and percent S (plaster of paris). Gypsum fertilizer usually has other impurities so grades are approximately 22 percent Ca and 17 ...
