METHOD FOR PRODUCTION OF CONSTRUCTION CERAMIC ITEMS Russian patent published in 2010 - IPC C04B33/02 

FIELD: construction.

SUBSTANCE: method for production of construction ceramic items includes preparation of raw materials, serpentine-containing coproducts and clay of various chemical-mineralogical composition, mixing, tempering with water, moulding of products by method of plastic technology, drying and baking. At the same time water for tempering is heated up to 40-45°C, and then with the help of electrolysis it is saturated with ions of electrode metals Al³⁺, Fe³⁺, Cu²⁺ to efficiency of water electric activation by metal ions of not lower than 40%.

EFFECT: improved strength, water absorption, average density, frost resistance, lower cracking and shrinkage of items.
