A range of liquids and gases can be carried in a tanker truck. These include gasoline, diesel and other liquid fuel products. They can be used to carry alcohol and most flammable or combustible fluids. Tanker trucks are sometimes used to transport non-flammable liquids such as milk or molasses.
Simply put, many mobile cement mixers contain a separate water tank inside the back of the truck. This enables the driver to mix water with the dry ingredients-aggregate and cement-whenever necessary. For maximum results, the driver will release the water to mix the cement when just a few kilometres from the job site. Doing this ensures that the cement is mixed properly and ready for use.
