Cement. 1  Cement is a binder. Similar to flour in a recipe, the purpose of cement is to hold the other materials together. 2  Concrete is a composite of aggregate (such as sand or gravel), cement, and water.

Concrete is a mix of cement, sand, and coarse stone. When wet, itâs pretty thin. Mortar is a mix of cement, sand, and limestone and itâs much thicker than concrete. Mortar is used to hold things like bricks and stones together. Iâm probably going to forget all that and just ask the guy who works at Home Depot the next (first) time I need cement, concrete, or mortar but hey, the more you know.
