This article is focused on lightweight aggregate-concrete modified by municipal sewage sludge and lightweight aggregate-concrete obtained from light aggregates. The article presents laboratory examinations of material physical parameters. Water absorptivity of the examined material was decreased by the admixture of water emulsion of reactive polysiloxanes. Water transport properties were determined using Time Domain Reflectometry, an indirect technique for moisture detection in porous media. Together with basic physical parameters, the heat conductivity coefficient λ was determined for both types of lightweight aggregate-concrete. Analysis of moisture and heat properties of the examined materials confirmed the usefulness of light aggregates supplemented with sewage sludge for prospective production.
本文聚焦于由城市污水污泥改性的轻集料混凝土以及由轻集料制成的轻集料混凝土。文章介绍了材料物理参数的实验室检测。通过添加反应性聚硅氧烷水乳液降低了被检测材料的吸水性。使用时域反射仪测定水传输特性，这是一种用于检测多孔介质中水分的间接技术。除了基本物理参数外，还测定了两种类型轻集料混凝土的导热系数λ。对被检测材料的水分和热性能分析证实了添加污水污泥的轻集料在未来生产中的实用性。
