The study assessed the possibility of using waste glass cullet from the screen part of CRTs (cathode ray tube) in the vitrification of asbestos-cement materials (ACM). The composition consisting of 50% by mass ACM and 50% by mass cullet was subjected to vitrification. The research material before and after vitrification was subjected to comparative analysis. As a result of vitrification, a transparent amorphous material was produced with a hardness about 7% higher than that of CRT glass and lower ion leachability in an aqueous environment compared to ACM. X-ray and spectroscopic examinations did not reveal the presence of chrysotile, i.e. a type of asbestos found in ACM. This fact proves that during vitrification the asbestos decomposed and formed a lattice of glass composed of the products of this decomposition. Moreover, the presence of heavy metals in the vitrified product was found, including Ba and Sr, the source of which was the CRT cullet. The obtained research results prove that ACM vitrification with CRT cullet leads to the effective utilization of both types of waste during one technological process. Therefore, the vitrification of ACM can be successfully carried out using waste CRT glass, and the harmless product obtained in the vitrification process can be used in practice. The use of CRT cullet in the vitrification of asbestos-cement materials will also have a positive impact on the environment as it will reduce the amount of electronic waste deposited in landfills.

该研究评估了在石棉水泥材料 (ACM) 玻璃化中使用 CRT（阴极射线管）屏幕部分的废碎玻璃的可能性。将由50质量％ACM和50质量％碎玻璃组成的组合物进行玻璃化。对玻璃化前后的研究材料进行对比分析。作为玻璃化的结果，产生了一种透明的无定形材料，其硬度比 CRT 玻璃高约 7%，与 ACM 相比，在水性环境中的离子可浸出性更低。X 射线和光谱检查没有发现温石棉的存在，即在 ACM 中发现的一种石棉。这一事实证明，在玻璃化过程中，石棉分解并形成了由分解产物组成的玻璃晶格。而且，发现玻璃化产品中存在重金属，包括 Ba 和 Sr，其来源是 CRT 碎玻璃。获得的研究结果证明，用 CRT 碎玻璃进行 ACM 玻璃化可以在一个工艺过程中有效利用两种类型的废物。因此，利用废弃的CRT玻璃可以成功地进行ACM的玻璃化，并且在玻璃化过程中获得的无害产品可以用于实践。在石棉水泥材料的玻璃化过程中使用 CRT 碎玻璃也将对环境产生积极影响，因为它会减少堆积在垃圾填埋场的电子废物量。获得的研究结果证明，用 CRT 碎玻璃进行 ACM 玻璃化可以在一个工艺过程中有效利用两种类型的废物。因此，利用废弃的CRT玻璃可以成功地进行ACM的玻璃化，并且在玻璃化过程中获得的无害产品可以用于实践。在石棉水泥材料的玻璃化过程中使用 CRT 碎玻璃也将对环境产生积极影响，因为它会减少堆积在垃圾填埋场的电子废物量。获得的研究结果证明，用 CRT 碎玻璃进行 ACM 玻璃化可以在一个工艺过程中有效利用两种类型的废物。因此，利用废弃的CRT玻璃可以成功地进行ACM的玻璃化，并且在玻璃化过程中获得的无害产品可以用于实践。在石棉水泥材料的玻璃化过程中使用 CRT 碎玻璃也将对环境产生积极影响，因为它会减少堆积在垃圾填埋场的电子废物量。
