d1) In the production of putties, adhesives and insulating masses, the share of fibrous waste is 40-50%. The products obtained are used for joining insulating products, sealing of partitions, joints and expansion joints.
d2) In turn, in the production of heat-resistant panels and casings, the share of waste is 15-20%. Such panels can be used as fire protection of steel constructions.
d3) Granulated wool from stone fibers is used in building industry to insulate partitions, openings, crevices and cavities.
The utilization of fibrous waste through briquetting allows them to be melted in shaft furnaces in order to produce melted products. In turn, the most important direction for the management and disposal of glass fiber waste is the production of acid-resistant putties or acid-resistant, clinker and stoneware products. Fiber glass waste is used as a flux. This type of waste is used in the manufacture of insulation boards as well as in the ceramization process. Fiber glass waste is used as an addition to the production of particular types of melted products. These waste, after crushing to below 2 mm, can be used as a basic component of acid-resistant putties. These kits are produced with the addition of soda or potassium glass. It is also possible to produce insulating boards on an inorganic bond from these wastes. They can also be used as an additive in the production of acid-resistant stoneware and clinker products, as well as in addition to brick masses. In addition, glass products made of container glass, e.g. candles or foam glass, can also be produced from said fibrous waste. An important direction for waste management of mineral wool, both stone and glass, is their disposal in the ceramization process. In order to determine the economic feasibility of using waste rock fibers, longitudinal cutting dust of the products on the mineral wool process line has been subjected to laboratory tests. They consisted in adding waste fibers to construction ceramics. Properties of the obtained materials with the addition of mineral fiber are presented in tab. 3. The analysis of these properties shows that the addition of 5% and 10% of waste stone fibers in relation to the base sample does not change the compressive strength to such an extent that would indicate deterioration of the quality of the products. The waste stone fibers were also subjected to industrial tests, the purpose of which was to check the correctness of technological assumptions, developed on the basis of laboratory tests. These tests consisted in the use of these fibers for the production of bricks. The process of manufacturing ceramic building materials was carried out in accordance with the technological regime applicable in the brickyard. Due to the difficulties associated with the dosing of fiber wastes, their share in the raw material set ranged from 1.5 to 4.5% by weight. A study of physical and mechanical properties was carried out to assess the quality of bricks with the addition of stone fiber. Burnt construction ceramics were subjected to open porosity, apparent density, water absorption and compressive strength tests. Properties of bricks received are shown in tab. 4. The analysis of these properties shows that the addition of 1.5% and 4.5% fiber waste increases the compressive strength. It is worth mentioning, however, that the addition of 6% by weight of these fibers resulted in a significant reduction in strength.
After prior fragmentation of such waste, a special granulate is created, which is then used as an addition to materials such as cement or bricks. However, mineral insulation is not only natural ingredients, but also a type of binder, which is a chemical compound and must be processed into specially prepared treatment centers. Stone wool producers are generally open to further develop their facility and to take up new tasks associated with this innovation process.
