Abstract
The task is solved in connection with Ministry of Industry and Trade project which is involved in development of a complex building programme based on high quality gypsum binder from secondary raw materials. Within one of sub-stages a solution of production of small plaster elements is subject of the project which should present a basic unit for construction of interior plaster partition walls. In the framework of the task a cast of plaster shaped block was carried out using a pilot form of own production. A plaster produced in optimised pilot way from the synthetic gypsum modified with plasticizer and retarding additive was used as a filler binder. After demoulding the produced block was exposed in laboratory environment and tested for setting of selected required properties according to standard EN 12859 (dimensions, density, flatness, tensile strength on bend, pH).
