(57) A concrete transport vehicle and a method for transporting concrete from a concrete batching plant to placement point on a construction site. The vehicle comprises an agitator (1); a pumping apparatus (3) comprising a feed hopper (4), a concrete pump (5) and a first pipeline (6); and a knuckle boom (7) provided with a second pipeline (8), which can be connected to the first pipeline (6) to convey concrete to a placement point. The concrete transport vehicle comprises a third pipeline (9), one end of which can be connected to the first pipeline (6) and whose other end extends to a point close to the charge and discharge hole (2) of the agitator (1), and valve means (10) for passing concrete optionally from the first pipeline (6) into the second pipeline (8) of the knuckle boom (7) or from the first pipeline (6) into the third pipeline (9) leading into the agitator (1).
