ORGANIC MINERAL MODIFIER FOR CONCRETE MIXTURES AND CONSTRUCTION MORTARS AND METHOD OF ITS PRODUCTION Russian patent published in 2010 - IPC C04B22/06 C04B24/16 C04B103/30 C04B103/60 

FIELD: construction.

SUBSTANCE: method for production of organic mineral modifier for concrete mixtures and construction mortars includes mixing of the following components, wt %: fine-grained active pozzolana additive on the basis of silica 25-51, microfiller which does not contain silica and does not have pozzolana activity, 40-60, superplasticiser 5-20, in mixer till final homogenisation with compaction of finished product till apparent density of at least 650 g/m³ at the following ratio of components. Organic mineral modifier is characterised with above described method.

EFFECT: reduced water demand of concrete and mortar mixtures, increased persistence of their mobility, provision of stable strength gain under conditions of drying.
