The disposal of leftover concrete and waste wash water from ready-mix concrete trucks is becoming an increasingly greater environmental concern. When an empty 9m readymix truck returns to the batch plant from the construction site, there is still approximately 200 to 400 kg of concrete adhering to the inside of the drum and mixing blades. It takes approximately 700 to 1300 L of water to wash ...
