- 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.
