Ready mix concrete delivered by cement mixers is sold by the cubic metre of volume. Typically a cement mixer will hold between 6 and 8 cubic metres of concrete, though as little as half a cubic metre can be ordered.
A cubic metre of concrete weighs approximately 2.4 tonnes, or around 20 wheel barrow loads.
Calculate the quantity in cubic metres of concrete required by simply multiplying the length and width of the area to be covered by the depth of pour.
