METHOD OF PREPARING FIBRE-REINFORCED FOAM-CONCRETE MIXTURE Russian patent published in 2025 - IPC C04B28/04 

FIELD: construction materials.

SUBSTANCE: invention relates to the industry of construction materials, specifically to methods of making structural and heat-insulating materials from cellular concrete using dispersed reinforcement with synthetic fibre. Method of preparing the fibre-reinforced concrete mixture by mixing water, foaming agent, dispersed reinforcement, mineral binder and fine aggregate. First, water and foaming agent are mixed in a separate container, and mixing is carried out in one turbulent mixer in the following order: a mixture of water with a foaming agent, portland cement, fine aggregate, dispersed reinforcement, wherein disperse reinforcement used is polyamide or propylene fibres with length of 12 mm, portland cement is used of 500 grade, as fine aggregate – flue ash of thermal power plant or quartz sand with fineness modulus of 0.2, at a certain ratio of components.

EFFECT: obtaining cellular concrete in a wide range of densities with given properties.
