The Differences Between Cement, Concrete, and Mortar

Adding water to this mix activates the cement so that it hardens, or cures, just as with concrete. Mortar is not as strong as concrete and typically is not used as a sole building material. Rather, is it the "glue" that holds together bricks, concrete block, stone, and other masonry materials.
