| Abstract [eng] |
The master's final project studies refractory plaster of wooden structures. The possibility of using fire-resistant plasters for passive fire protection of wooden structures cultural heritage values are considered. The methodical part of the work reviews regulatory requirements for fire resistance of structures, the importance of passive fire safety for the protection of the values of wooden structures cultural heritage, describes the use, composition, and properties of ordinary and refractory plaster. The procedure and equipment for the testing of plasterboard are given. In the practical part of the research work, refractory plaster is produced from environmentally friendly secondary industrial waste using a geopolymer binding agent and its product, geopolymeric concrete. The composition of the plaster and other components that improve the mechanical and thermal insulation properties of the coating are described. The experimentally determined the mechanical, thermal insulation properties of the refractory plaster, the influence of plaster on the burning point of the wooden structure. Increasing the fire resistance of wooden structures is topical in order to preserve wooden cultural heritage values for the needs of society. Research and use of refractory materials extend the use and passive protection of structures. |
