Batcher plant for producing ready-mixed concrete
 A batcher plant for producing ready-mixed concrete is miniaturized by disposing, side by side on a trestle, a cement-paste making unit with cement measuring means and a stationary cement-paste mixer and an aggregate processing unit with fine and coarse aggregate receptacles. Cement paste prepared by the cement-paste making unit is admitted from the cement-paste mixer into a mixing drum of a truck mixer independently of admission of mixed fine and coarse aggregates quantitatively measured by the aggregate receptacles, so that the loading of concrete materials in the truck mixer can be effectively carried out without loss of efficiency caused by waiting time.
