High-strength modified arbolite for volumetric blocks in modular construction
Incoming article date: 18.11.2025The development of remote and hard-to-reach territories of Russia requires effective construction solutions that combine high performance, environmental friendliness, and full factory readiness. This article presents the results of a study on modified arbolite designed for use in the production of volumetric spatial modules. To improve the physico-mechanical properties of the conventional composition, a comprehensive chemical modification of the wood aggregate was applied, including preliminary treatment with aluminum silicate (Al₂SiO₅) followed by the introduction of ethanedioic acid into the mixture. It has been experimentally established that the proposed modification leads to a statistically significant reduction in the average density of the material by 11%, while simultaneously increasing the compressive strength by 47% compared to control samples. The physico-chemical strengthening mechanism, consisting in the formation of an organo-mineral framework within the wood structure, is substantiated. The results demonstrate the high potential of the developed material for use as a structural and insulating component in modular construction for regions with extreme climatic conditions.
