The Differences Between Cement, Concrete, and Mortar

2021-6-30  The Spruce / Liz Moskowitz. Concrete . Concrete is a complete building material used for foundation walls, concrete slabs, patios, and many other masonry structures. It is uniquely versatile because it starts out as a simple, dry mixture, then becomes a flexible, semi-liquid material capable of forming into any mold or shape, and which dries into the hard-as-rock material we know as concrete.
