METHOD OF THERMAL TREATMENT FOR CONCRETE AND REINFORCED CONCRETE ARTICLES Russian patent published in 2014 - IPC C04B40/02 

FIELD: heating.

SUBSTANCE: invention relates to construction industry, namely, to the methods of concrete thermal treatment and can be used in construction for manufacturing of precast concrete or reinforced concrete items and structures. The method of thermal treatment for concrete and reinforced concrete items implies cyclic heating by supplying saturated steam, switching the steam supply off, maturing of items, repeated supply of saturated steam, switching the steam supply off, maturing of items up to their cooling. In the first cycle the saturated steam is supplied up to reaching the medium's temperature of 30°C for 0.5 hours, isothermic maturing of items is carried out under the temperature of 30°C for 2.5 hours, in the second cycle the saturated steam is supplied up to reaching the medium's temperature of 40°C for 0.5 hours and isothermic maturing of items is carried out under the temperature of 40°C for 5.5 hours.

EFFECT: invention allows for boosting of concrete strength gain.
