Abstract: The present invention relates to a new method and system for reclaiming and recycling the concrete residue that remains on key components of a concrete mixing truck in a safe and environmentally responsible manner. Any slurry aggregate remaining on the chutes or other parts of the concrete mixing truck is collected by a concrete collection system that is attached to the concrete mixing truck and includes an augur conveyor enclosed in a housing, whereby the augur conveyor is hydraulically extended either behind or in front of the chutes of the concrete mixing truck depending on a type of mixing truck. The augur conveyor can be raised to a maximum height in order to discharge any collected slurry aggregate from the chutes or other parts of the truck back into a top hopper of the concrete truck to be directed back into the mixing drum of the concrete mixing truck.

Abstract: A protective coating, underwater applicator including a housing for receiving an underwater protective coating compound; a nozzle on a distal end of the housing having an end opening for applying the protective coating; a spatula extending from one portion of the end opening for spreading the protective coating; and a seal disposed about a substantial portion of the end opening for preventing the loss or coagulation of the protective coating.
