DIY CONCRETE:: How-To-Mix Concrete : 5 Steps

How a concrete mixer works: The drum of the mixer has fixed paddles attached to the inside. When the mixer is rotating, these paddles pick up the concrete, pull it to the top, and then gravity lets it fall down on itself. This churning motion mixes the concrete. If the drum of the mixer is tilted up vertically, the churning motion can't happen.
