METHOD OF UNIFORM HEATING OF CONCRETE MIXTURE Russian patent published in 2020 - IPC B28B17/02 B28B7/42 

FIELD: construction.

SUBSTANCE: invention relates to construction, namely to production of reinforced concrete articles and structures, and can be used for electric heating of concrete and other conductive building mixtures on construction sites and factories of construction industry. Method of uniform heating of concrete mixture consists in fact that concrete mixture is placed in a container for heating with electrodes stationary in its walls, to which electric current is supplied, wherein during heating of concrete mixture at specified time intervals by polling temperature sensors, distributed uniformly by volume of capacity and placed on rods, fixed in cover of container, measuring the temperature distribution in the volume of the concrete mixture, determining the average temperature of the concrete mixture, comparing the measured temperature of the concrete mixture in the area of placement of each temperature sensor with the value of average temperature of the concrete mixture, determining the temperature deviation in each measurement point of the sensor from the average in volume and in the presence of temperature deviation values greater than or equal to a predetermined maximum allowable value, depending on the temperature deviation sign using the control unit, respectively, reducing or increasing the value of the current flowing through the areas with temperature deviation exceeding the maximum permissible value.

EFFECT: enlarging the range of methods for electric heating of concrete mixtures, as well as providing uniform heating of the mixture throughout the volume.
