The dispenser includes at least one tank preferably a central tank holding powdered material such as cement powder dispensed through chute (44) by virtue of a paddle wheel dispenser (41). Water tanks which dispense water through outlet (50) are located either side of the cement powder tank. A common drive shaft (47) drives augers (35) and (36) and the paddle wheel (41). The dispensing of material is controlled by controllers (52) and (53) such that a predetermined ratio of material can be dispensed into, for example a mixer. - The dispenser (30) is located in the rear of a tipping body such as a tip truck body (31). When the tipping body is inclined gravity causes bulk material held in the tipping body either side of partition (32) to feed augers (35) and (36).
