CONSTRUCTION MIXTURE FOR PRODUCTION OF PAVING SLABS WITH SHUNGITE AGGREGATE AND METHOD FOR MANUFACTURING PAVING SLABS USING SAME Russian patent published in 2025 - IPC C04B28/04 E01C5/06 

FIELD: construction.

SUBSTANCE: group of inventions relates to the construction industry and can be used in making construction mixtures for making concrete articles, decorative slabs, road and sidewalk pavements. Invention includes a construction mixture for making paving slabs with shungite aggregate and a method of producing paving slabs using the construction mixture. Construction mixture for the production of paving slabs includes shungite filler with fraction of 0.1-8 mm – 30-73.8 wt.%, portland cement – not less than 20 wt.%, quartz sand – 0.1-43.9 wt.%, finely ground shungite powder with particle size from 0.1 to 63 mcm – 2-5 wt.%, modifying additives (LST or plasticisers) – 0.1-0.5% of weight of portland cement, water – balance. Method of producing paving slabs includes: preparing a pressed construction mixture, pressing the mixture under high pressure, palletizing the formed tiles and holding the moulded paving slabs.

EFFECT: obtaining concrete paving slabs (stone blocks) with shungite filler and finely ground shungite with particle size from 0.1 to 63 mcm, with preservation and improvement of its physical and mechanical properties.
