Abstract

The invention refers to a method of producing concrete in a mobile computer controlled concrete station (22) for the production of concrete mixtures, comprising cement, aggre­ gate material of gravel and sand, and water, with or without superplasticizers. In the concrete station, that is realized for computer control of the mixing processes, the aggregate material is supplied to a telescopic sorter device (2) for screening and distributing the aggregate material according to size to a plurality of collecting cells (3). A system of trap doors (4) and valves (5) in co-operation with electronic equipment for the weighing of the aggregate material in exact proportion by means of a weighing drum (6), is computer controlled. The content of the weighing drum (6) is transferred to a mixer drum (7) by pneumatic means. A preprogrammed amount of water, and, if desired, amounts of superplasticizers are supplied from tanks (12) to the mixer drum through pipes. The mixer drum is provided with means for electric measurement of the ZETA-potential difference or of the conductivity in the cement paste. Using these measuring quantities and nominal values for water and for the used kind of superplasticizers, the consistency of the mix can be controlled through computer controlled supply of water and superplasticizers under due observance of said nominal values.
