dc.abstract.enThe leading theme of the paper was to study, how the use of lightweight concrete based on waste aggregates, characterized by significant mechanical strength and increased thermal insulation, affects the properties of building partitions and contributes to possible economic savings, so as to properly design and select materials required for the construction process. The work presents the composition of lightweight concrete samples made of waste lightweight aggregates as well as their physical and mechanical properties. It includes calculations concerning floor loading and heat transfer coefficient of building partitions made of the presented lightweight concretes. Calculations provided the basis for assessing the impact of particular parameters on compressive strength and thermal insulation of walls and floors. The paper additionally describes concretes made of waste aggregates in the form of lytag (Pollytag) and slag. Based on the research, it was found that concrete containing Pollytag had the lowest density value and thermal conductivity coefficient. These parameters translated into reduction in the weight of the slab in question by more than 40% and allowed to save 25% of steel compared to an analogous plain concrete slab. The decrease in heat conductivity coefficient did not result in a significant increase in thermal insulation of building partitions.
