In this article the relevance of development of the wood concrete meeting the modern requirements for an ecological component and energy efficiency is considered. Features of the mechanism of structurization at hydration of the cement knitting and organic filler with use of the X-ray diffraction analysis are shown. Indicators of concentration of basic elements in the cement test without organic filler are defined and at his existence. The comparative analysis of structure of steam solution of wood concrete and structure of solution from quick-hardening cement with use of data of a rastroelektronny microscope is carried out.
