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.
Gypsum block Gypsum block is a massive lightweight building material composed of solid gypsum, for building and erecting lightweight fire-resistant non-load bearing interior walls, partition walls, cavity walls, skin walls and pillar casing indoors. Gypsum blocks are composed of gypsum plaster, water and in some cases additives like vegetable or wood fiber for greater strength. Partition walls made from gypsum blocks require no sub-structure for erection and gypsum adhesive is used as bonding agent, not standard mortar. Because of this fundamental difference, gypsum blocks shouldn't be confused with the thinner plasterboard (also known as wallboard or gypsum board) used for paneling stud walls.
