FIELD: construction.
SUBSTANCE: invention relates to the field of construction, in particular to methods for preparing mixtures containing astringent components, for example concrete. Method for producing a concrete mixture with the utilization of the previously produced residues of this mixture comprises the following steps: in the tank with recyclable residues of the concrete mixture, the composition of which is known, load the amount of inert components included in the composition of the recycled residues of the concrete mixture specified by the process control system, and the walls of the tank are cleaned of the recyclable residues of the concrete mixture by mechanical action, thus obtaining a mixture of inert components with recyclable residues of the concrete mixture; resulting mixture is loaded into the mixer, releasing the reservoir, weighed the mass of this mixture in the mixer and stores the obtained data in the process control system; after dry cleaning of the tank walls, the amount of water set by the process control system is poured into the freed tank to further remove the recycled concrete mixture remaining in the tank from the tank walls; resulting mixture is charged to a mixer; reweighting is carried out, which allows to determine the total weight of the loaded mixture after dry cleaning together with the mixture after wet cleaning, and storing the obtained data in the process control system; process control system based on the obtained data of the results of weighing the mixer in the preliminary stages and information on the loaded amount and composition of the inert components and water determines the number of necessary components for the production of a concrete mixture with a specific composition of components required for loading into the mixer; additional components in the required quantity are loaded into the mixer and mixed to produce a concrete mixture.
EFFECT: invention simplifies the technological cycle of recycling the remains of a concrete mixture.
