Foam concrete made from extruded wood fibers

Relevance of the study is determined by the need to develop new thermal insulation materials that can ensure comfortable thermal and humidity conditions, be environmentally friendly and modern, while having characteristics, similar to wood and safe for human health. The article proposes the development of a new solution for producing thermal insulation material using magnesiumbased binder and extruded wood fiber. A series of experiments was conducted with extruded fiber using different binders and foaming/gasforming methods: 1) Portland cement with the use of synthetic foaming agent; 2) magnesium cement with the use of synthetic foaming agent; 3) magnesium cement with gas formation using aluminum powder and sodium hydroxide. The conducted research has shown that insulation based on magnesium cement and wood fiber can be effective in conditions requiring high fire resistance, resistance to biological impact, and creation of comfortable thermal and humidity regime, especially for filling walls of frame houses.
