  • The Differences Between Cement, Concrete, and Mortar

    The terms cement, concrete, and mortar can be confusing to DIYers, who may lump them all together as being messy substances used in masonry that harden to form a flat surface or to bind one object to another. The terms are often used interchangeably—and inaccurately. Though the terms are often used synonymously, cement, concrete, and mortar are actually three distinctly different materials:
