METHOD OF PRODUCING CONSTRUCTION ARTICLES FROM LIGHT CONCRETE ON ORGANIC FILLER OF VEGETABLE ORIGIN Russian patent published in 2019 - IPC C04B16/02 C04B18/26 C04B28/10 C04B40/02 

FIELD: construction.

SUBSTANCE: invention relates to the industry of construction materials and can be used in production of construction articles using vegetal raw material processing wastes, particularly wood waste. Method for production of construction articles from light concrete on organic filler of plant origin includes preparation of concrete mixture from binder - lime, preliminarily prepared organic filler of vegetable origin and water, stirring, supply of concrete mixture, moulding and compaction of mixture, treatment of moulded articles with carbon dioxide, their decalcification, wherein the concrete mixture is prepared from an organic aggregate of vegetable origin in amount of 85, 80, 75 or 70 wt. % of dry substance, slaked lime in amount of 15, 20, 25 or 30 wt. % of dry substance, water in amount of 27, 25, 23 or 21 % over 100 % mixture of raw components, supply of concrete mixture is carried out before mould filling, moulding mixture is carried out in mould, its compaction is carried out in mould by pressure moulding, for example, 1.0 MPa, and hardening of articles is carried out in a mould by forced carbonisation with carbon dioxide concentration of 5 to 95 % for 8–10 minutes. Organic filler of vegetable origin is represented by wastes from wood processing from lumber wastes of sawmilling, timber harvesting and woodworking, with stems of cotton and sunflower, from rice straw, grain husks, cannabis and flax bonfires.

EFFECT: technical result is reduction of time of hardening and hardening of articles, low cost and increased efficiency of method of producing articles, recycling wastes.
