Zusammenfassung:The experimental results of physical-chemical properties of composite materials on the basis of cement and wood waste modified by an aquatic solution of oxalic aldehyde are presented in this paper. The injection of a chemical addition agent being in optimal concentration is shown to result in the increase of compressive strength of a cement stone by 30%, that of wood-cement composition – in 7 times. IR spectroscopy investigations, microphotographs of structures, kinetics of samples strength changes are shown.
