Abstract (en)
[origin: EP0509502A1] The method for repairing concrete by means of machine application of PCC mortar and, if appropriate, subsequently PCC stopper by the wet casting method consists in that the made-up PCC mortar is applied by means of compressed air successively in a plurality of layers at different, progressively lower speeds through an elongated nozzle, whereupon, if appropriate, the PCC stopper is applied at relatively low speed and, if desired, is superficially smoothed or textured. The apparatus comprises a mixing and pumping device for mortar as well as a special nozzle having a central entry for compressed air, a control device for stepless metering of the compressed air and an elongated outlet tube. <IMAGE>
