The use of mineral waste for the production of lightweight artificial aggregate is an important element of activities for sustainable development in construction and the implementation of the objectives of the circular economy. The article presents the physical, mechanical, and ecological properties of an innovative artificial aggregate produced from bottom sediments, concrete dust, and municipal solid waste incineration fly ash. The obtained research results confirm that the developed material achieves technological properties comparable to artificial aggregates available on the market, both commercial and those derived from recycling. However, the increased leachability of chlorides and sulphates remains a significant challenge, which may limit the scope of its applications. Despite this, the material shows the potential for use, among others, in the production of lightweight concrete. The analyses carried out have shown that the thermal hardening processes (200-400 °C) and autoclaving do not guarantee full immobilization of harmful substances contained in the raw materials for the production of this type of aggregate.
将矿物废料用于生产轻质人造骨料是建筑领域可持续发展活动以及实现循环经济目标的重要组成部分。本文介绍了一种由底泥、混凝土粉尘和城市固体废弃物焚烧飞灰制成的创新型人造骨料的物理、力学和生态特性。所获得的研究结果证实，所开发的材料具有与市场上现有的商业人造骨料以及回收人造骨料相当的技术性能。然而，氯化物和硫酸盐的浸出性增加仍然是一个重大挑战，这可能会限制其应用范围。尽管如此，该材料显示出在生产轻质混凝土等方面的应用潜力。所进行的分析表明，热硬化过程（200-400°C）和蒸压处理并不能保证完全固定生产此类骨料的原材料中所含的有害物质。
