Strength and Deformability of Mineral Wool Slabs under Short – Term Cyclic Compression

The strength and deformability of mineral wools slabs, as well as thermo-insulating characteristics can be attributed to the most important indices determining the popularity of these products in practice. The mechanical resistance and stability of mineral wool slabs in use (at construction) of buildings, as well as the requirements for energy saving and heat conservation are in most cases related to the essential requirements set for a building. The mechanical characteristics of mineral wool slabs are subject to structure, density of material, percentage of binder in product, as well as production techniques. The deformability of mineral wools slabs is determined by mobility of fibrous structure, which is best observed under compression by short-term loads. The article considers the strength and deformability properties of mineral wool products under compression by short-term cyclic load. The results obtained while investigating the compression of mineral wool slabs can be applied for determination of fields and conditions for use of such products in constructions of buildings (floors, ceilings, roofs), as well as for substantiation of respective technical requirements in the normative documents for design of these constructions.
