Gypsum
Gypsum was formed by sedimentary deposition processes. In order to use gypsum as a building material, the crushed and ground gypsum is dried in a kiln. Depending on the temperature of the kiln, different building gypsums for different properties are produced. Burned gypsum as a dry, powdery product is used as a binder, for example, in plaster or screed. Before processing, these dry products are mixed again with water.
Gypsum, plaster and gypsum screed but also gypsum boards, essentially consist of building gypsum (binding agent) and sand.
Gypsum is also added to the cement and acts as a setting retarder during the hardening of the concrete.
Toni Technik offers an extensive range of solutions in the field of binding agent testing for the building material industry as well as for the R&D sector. In order to test compressive strength; which is in most cases below 100 kN our ToniZEM can be used. The setting time can be determined according to EN 13279-2 or ASTM C 472 with our automatic Vicat devices.
