PRODUCTION OF SELF-COMPACTING SUPER STRONG REACTIVE POWDER FIBRO-MORTAR WITH HIGH FLUIDITY AND METHOD FOR PRODUCTION OF CONCRETE ARTICLES FROM SAID MIX Russian patent published in 2014 - IPC C04B28/04 C04B111/20 

FIELD: process engineering.

SUBSTANCE: this invention relates to production of construction materials and can be used for fabrication of concrete articles: decorative open-work guards and grates, fine pavement plates and edge stones, etc. This method consists in mixing of components to required fluidity mix. First, water and super plasticiser are mixed in the mixer. Then, added are cement, micro silica, rock dust and mixed for 2-3 minutes. Now, added are sand and fibre and mixed for 2-3 minutes. The following components result: Portland cement PC500D0, sand of 0.125-0.63 fraction, super plasticiser, fibres, micro silica, rock dust, hardening promoter and water. Production of concrete articles in moulds consists in preparation of mortar, mix feed to moulds and curing in evaporation chamber. Mould inner working surface is processed with fine ply of water. This mould filled, thin ply of water is sprayed on mix surface and mould is closed by temporary trough.

EFFECT: higher fluidity, strength, lower costs, possibility of production of open-work articles.
