Development of Thermal Insulating Plasters with Regulated Capillary Activity

Abstract:

The development of prospective, thermal insulating plasters that are applied during the reconstruction and rehabilitation of structures has taken place at the Faculty of Civil Engineering for many years. The main objective of the research work is to achieve the best ratio of thermal and mechanical properties, including high porosity. During the development of this test, testing recipes were tested, which were often used as alternative input materials. On the basis of the achieved results, optimal recipes were proposed with the stated requirements for heat insulation, mechanical properties and porosity. Due to the fact that during the reconstruction this often concerns structures loaded by increased structure, then such materials must have high open porosity. The article describes the study of moisture behaviour, particularly capillary activity for light thermal insulating plasters with the use of alternative raw material sources.
