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.

2018-9-30  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.

Experiment-8-Fineness-of-Lime-Gypsum-and-Cement

Fineness of cement: it's an indicator to the size of cement particles. Cement is considered fine if the percentage of weight retained on sieve #170 is less than 10%. Fineness of gypsum: it's an indicator to the size of gypsum particles. Gypsum is considered fine if the percentage of weight passing sieve #14 is 100% and the percentage of weight passing sieve #100 is more than 75%.
