Portland cement mortar, simply known as cement mortar, is a mixture of Portland cement, sand, and water (plus additives, if any). It is the most common mixture used today for making mortar, a workable paste that is used to set blocks and bricks. Cement mortar must be mixed just before use so that it does not cure prematurely. For this reason, it is beneficial to learn how to mix Portland mortar yourself. The process is fairly straightforward and requires only a few tools and supplies.
