Detailed explanation of masonry mortar

Uses of masonry mortar

Masonry mortar is the mortar used for laying various block building materials such as bricks, stones, and blocks. It is called masonry mortar. Masonry mortar can be used to bond a variety of bricks, autoclaved gray bricks with low water absorption, clay bricks with strong water absorption, and aerated lightweight concrete bricks. It plays the role of bonding structural masonry, lining leveling, and transmitting load. It is an important part of masonry.

Types of masonry mortar

There are three types of masonry mortar: lime mortar, cement mortar, and mixed lime mortar. It is made of lime plaster, sand or cement in a certain proportion and is generally used for masonry and plastering layers that do not require high strength and are not subject to moisture. It is made by adding appropriate admixtures such as fly ash, diatomite, etc. into cement or lime mortar to save the amount of cement or lime and improve the workability of the mortar.

Advantages of masonry mortar

As an environmentally friendly green building material, masonry mortar has been widely accepted by the market and promoted by local governments under the current government order prohibiting on-site mixing.

The specific advantages are: (1) Excellent construction workability and bonding ability. Improve the workability of the masonry, make the vertical mortar joints of the masonry smeared, the mortar hanging evenly, the mortar joints slurry full, and at the same time increase the contact area between the mortar and the theme to ensure the stability of the masonry rotation.

(2) The excellent water retention enables the mortar to gel more densely under different conditions, and ensures effective bonding of the mortar on the dry block base surface. The mortar can solidify under more conditions, making the blocks and The blocks form a durable, stable and strong overall structure. The grouting method can also be used to build the wall to make the wall more homogeneous and evenly distribute the stress on the wall, thus greatly improving the integrity and stability of the wall.

(3) It has the characteristics of plastic shrinkage and low drying rate, ensuring the dimensional stability of the wall to the maximum extent.

(4) After gelling, it has mechanical properties of rigidity and toughness. Improve the wall's resistance to cracking, seepage and strain, so as to protect the wall from water erosion and damage.
