The possibility of using the waste from the production of mineral wool (MW) and nepheline-syenite (NS) in the production of ceramics in order to improve the physical and mechanical properties as well as the frost resistance of the samples was investigated. The use of NS in amounts 5 – 15% increases the compression strength of the samples to 17% and reduces the density, water absorption, and ultrasound speed in the samples to 5.2, 12.5 and 7% after firing at 1060°C. An increase in the NS amount due to an increase in the number of pores with diameters 0.02 – 0.1 μm in the samples promotes diminishes the damage to samples during freezing– thawing processes.

研究了将矿棉 (MW) 和霞石正长岩 (NS) 生产过程中产生的废料用于陶瓷生产的可能性，以提高样品的物理和机械性能以及抗冻性。在 1060°C 下烧制后，NS 的用量为 5-15%，可将样品的抗压强度提高至 17%，并将样品的密度、吸水率和超声速度降低至 5.2、12.5 和 7%。由于样品中直径为 0.02 – 0.1 μm 的孔隙数量增加，NS 量的增加促进了在冻融过程中对样品的破坏。
