What is the ratio of the building material that is named for the Latin word "crushed" and sand used to stabilize buildings?
Mortar (masonry) Mortar is a workable paste used to bind building blocks such as stones, bricks, and concrete masonry units together, fill and seal the irregular gaps between them, and sometimes add decorative colors or patterns in masonry walls. In its broadest sense mortar includes pitch, asphalt, and soft mud or clay, such as used between mud bricks. "Mortar" comes from Latin "mortarium" meaning crushed.
Rubble masonry Rubble masonry is rough, unhewn building stone set in mortar, but not laid in regular courses. It may appear as the outer surface of a wall or may fill the core of a wall which is faced with unit masonry such as brick or cut stone.
