Any man worth his salt should know the difference between cement, concrete, and mortar. I am not that man. Theyâre all just gray sludge to me. But This Old House explains the difference between the three in a very easy to understand way. Cement is a fine powder that hardens when mixed with water and is used in many building mixes. 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.
