CONSTRUCTION MATERIAL (VERSIONS) AND METHOD OF MAKING ARTICLES FROM SAID MATERIAL (VERSIONS) Russian patent published in 2012 - IPC C04B40/00 

FIELD: chemistry.

SUBSTANCE: invention is primarily meant to make construction articles such as blocks, partitions, walls and other building structures using ground organic filler in form of cellulose-containing wastes from crop husbandry and wood-processing industry. To obtain the initial moulding mixture, the cellulose-containing crop husbandry wastes used are the hard parts of the plants crushed to particles not bigger than 30 mm and dried to moisture content of not more than 10%, the wood processing wastes - industrial wood chips not bigger than 1 mm, the electrolyte used is liquid glass (Na₂SiO₃) in form of a 1.5-1.75% aqueous solution and the calcium-containing materials used are cement production wastes, calcite and limestone, which are dehydrated and crushed to powdered state. Versions of the construction material and the method of making articles from said material are described.

EFFECT: high strength, chemical resistance, sound-proofing properties and improved processability of the obtained articles.
