Information @ a Glance

  • Mortar is a workable paste used to bind construction blocks together and fill the gaps between them. The blocks may be stone, brick, cinder blocks, etc.
  • Mortar becomes hard when it sets, resulting in a rigid aggregate structure.
  • Modern mortars are typically made from a mixture of sand, a binder such as cement or lime, and water.
  • Mortar can also be used to fix, or point, masonry when the original mortar has washed away.
  • The first mortars were made of mud and clay. Because of a lack of stone and an abundance of clay, Babylonian constructions were of baked brick, using lime or pitch for mortar.
  • Portland cement mortar (is very often known simply as cement mortar) and is created by mixing Ordinary Portland cement (OPC), hydrated lime, and aggregate (or sand) with water.
  • In the United States (and other countries), one of five standard types of mortar (available as a dry premixed product) are generally used for both new construction and repair. The ratio of cement, lime, and sand included in each mortar type produces different strengths of mortar.
  • The Premixed mortar products are designated by one of the five letters M, S, N, O, and K, with Type M mortar being the highest strength and Type K the weakest. These type letters are taken from the alternate letters of the words "MaSoN wOrK".
  • Mortar can better resist chemical attack, staining, and freeze-thaw damage if it is less absorbent. Masonry cement mortars generally absorb only about half as much water as comparable non-air-entrained mortars.
  • The use of mortars in bulk silos (granel) offers many advantages for the contractors in terms of logistics and efficiency increase. There is a lot of potential throughout the world especially in urban agglomerations.
  • Dry mortars with highest production volumes worldwide are cement based renders (base renders, decorative renders, special renders etc.).
  • Portland cement-lime (PCL) is sometimes used in mortars. High-strength mortars with high Portland cement content are most effective when freeze-thaw action are expected to be high.
