FIELD: construction industry.
SUBSTANCE: raw mixture includes, as the bonding agent, quick-hardening cement M500 - 25-30%, ash after bituminous coals have been burnt - 25-35%, microsilica after silicon alloys have been smelted - 10-12%, complex additive "Relamix Type 2" for concretes and solutions - 0.6-0.8%, and mountain sand containing 10-15% of garnet minerals is the rest. The method involves pre-mixing of raw mixture till liquid mass is obtained, its laying on a tray, and drying. At that, on the first layer of pre-mixed raw mixture there laid is mesh reinforcement made from high-strength strands, and one layer of anhydrous or hemihydrate plaster is applied in quantity of 50-100 gram to one square metre of pre-mixed mixture. The second layer of pre-mixed raw mixture is laid on it, and it is subject to packing, hardening and drying processes.
EFFECT: improving material structural characteristics.
