Študij funkcionalnih lastnosti trajnostnih materialov, izdelanih na osnovi naravnih stranskih produktov in veziv z ničelno emisijo CO [sub] 2

This is a study of some key properties of sustainable materials based on natural by-products (straw or hemp shives) and binders with zero CO2 emissions (natural clay or CO2-activated binders based on by-products), which can be used in the interiors of building structures in the form tiles and suspended ceilings to stabilize their thermal and moisture properties and to adjust the acoustic properties. It is specifically a study of the acoustic properties of these natural based ecological composites and a study of their reaction to fire. These properties are key, together with hygroaccumulation properties, for the use of these materials in the field of building structures. The aim of the work was to determine the dependence of the type and dosage of the binder on the resulting behavior of the composites from the point of view of fire, and then further reactions of the action of fire on organic particles during short-term exposure to a small flame. Furthermore, it is about the results of the study of acoustic properties, from the point of view of sound absorption, as well as on the adjustment/stabilization of the relative humidity or fluctuations in the production of water vapor in the room (e.g., different short-term occupancy of the spaces by people). The results of this study provide important insights for optimizing the use of ecological composites in construction applications.
