FIELD: construction.
SUBSTANCE: invention relates to the field of construction and can be used in the manufacture of mortars and products, for example, brick, silicate concrete. Method for activating lime involves pretreatment of lime with a vortex layer of anisotropic ferromagnetic bodies in a nonmagnetic container located in an apparatus with an external electromagnetic field. In this case, lime is fed by a rotating screw through the inner cavity of a non-magnetic continuous tube to the zone of rotating anisotropic ferromagnetic bodies with a diameter of 1.2 mm and a length of 5–10 mm, having an energy saturation of the working zone of at least 100 kW/m3. Movement of bodies is provided by the apparatus with an external electromagnetic field. Axis of the cylindrical non-magnetic tube is made at an angle of 5–25º in the direction of lime supply.
EFFECT: method provides increased compression strength obtained on the basis of activated lime of lime mortar.
