Technology for producing of activated crushed stone from granite

Application: concrete production.

Advantages: the use of activated crushed granite in the concrete production allows: increase the strength of the concrete up to 30 % in the design of age; to increase the rate of strength development (including in the heat and humidity treatment) to 1.5 times; to reduce the consumption of cement in the 40–50 kg/m3; reduce costs by eliminating the plasticizers.

Key features: properties of activated crushed granite: size 5–20 mm; Group I (cube-shaped); F400; mark on the divisibility 1400; bulk density of 1580 kg/m3 according to GOST 8267-93.

Developed: Research Laboratory of Highway Engineering and Operation, Supervisor – Prof. Dr. Alexey Busel, D.Sc.
