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.
Zener ratio The Zener ratio is a dimensionless number that is used to quantify the anisotropy for cubic crystals. It is sometimes referred as "anisotropy ratio" and is named after Clarence Zener. Conceptually, it quantifies how far a material is from being isotropic (where the value of 1 means an isotropic material).
