Abstract
One-stage foam concrete technology and its impact on the quality of wall materials
Incoming article date: 07.07.2025A brief list of problems in the operational reliability of multilayer energy-saving walls is given, and the thesis is formulated that single-layer or equal-permeability multilayer walls may have better operational properties. Information about the equipment and technology for producing foam concrete mixtures using a one-stage method is provided. It is shown that the introduction of a fibrous filler instead of some of the sand significantly accelerates the phase transition of the mixtures from a viscous state to an elastic state and has a positive effect on the operational properties of the hardened foam concrete. The list of the material's investigated performance properties includes experimentally obtained indicators of sorption properties, equilibrium moisture content, thermal conductivity, and frost resistance of thermal insulation and structural-thermal insulation foam concrete containing different amounts of fibers of different lengths.
