Application: preparation of concrete mixtures, production of concrete products and structures.
Advantages: high quality of concrete and reduced consumption of cement.
Key features: the technique provides partial substitution of fine natural sand with large fractions of granite screenings. It allows to increase the strength of concrete on 20–50 %, to increase frost-resistance in 2–3 times, to increase resistance to salts and chlorides and water resistance, to reduce the consumption of cement up to 10–20 %.
Developed: Research and Testing Laboratory for Concrete and Constructive Materials, Supervisor – Prof. Dr. Eduard Batyanovsky, D.Sc.
