This paper presents mechanical and physical properties of light porous aggregates obtained from local waste materials. Granules were produced from a mixture of aluminosilicate-based coal-mine slates and car windshield glass that was contaminated by the polyvinyl butyral foil. The initial waste material ratio modification significantly alters physical and mechanical properties of obtained ceramic granules to the extent of the critical amount of added windshield glass powder. The temperature of the heat treatment affects the granules’ properties and demonstrates the microstructure and phase crystallization control possibilities. The critical value of the windshield glass concentration was determined to be at a level of 30%, considering the relationship between mechanical and physical properties when large porosity is essential in further application. On the other hand, if the glass-to-slates weight ratio was equal and a sufficient thermal treatment was applied, a core–shell macrostructure formation and occlusion of pores occurred.

本文介绍了从当地废物中获得的轻质多孔骨料的机械和物理性能。颗粒是由铝硅酸盐基煤矿板岩和被聚乙烯醇缩丁醛箔污染的汽车挡风玻璃制成的。初始废料比率的改变显着地改变了获得的陶瓷颗粒的物理和机械性能，达到了添加的挡风玻璃粉的临界量的程度。热处理温度会影响颗粒的性能，并证明其微观结构和相结晶控制的可能性。考虑到当进一步应用中必须具有大的孔隙率时，考虑到机械性能和物理性能之间的关系，确定挡风玻璃玻璃浓度的临界值为30％。
