Plastering mortar

Features and components

Mortar is defined as a used conglomerate material
in the construction sector to create, for example:

• Load-bearing and non-load-bearing walls;
• Internal and external walls;
• Internal and external plaster;
• Floors and walls.

To obtain the mortar, binding materials are used
(gypsum, cement, lime etc.) and inert materials, i.e. sand and water.

Let’s analyze them together…

Plastering mortar:
inert materials

The inert materials used to make the mortar have
the aim is to block the phenomenon of withdrawal and try to reduce the
possibility of crack formation.

Furthermore, the inert material represents the structure
load-bearing element of the mortar, occupying approximately 70% of its volume.

Finally, the aspects of the inert material to consider
I am:

1. The origin : it can be natural or artificial.
2. Purity : it is determined based on the quantity of salts and/or elements
   alterable on a chemical level, such as soft limestones which are inert
   contains.
3. The grain size : the larger the size of the inert material e
   the greater the resistance of the mortar, while the finer the aggregate will be
   the better the workability of the mortar will be.

Therefore, the results you can obtain will be:

• A fine-grained mortar: for
  create smooth plasters;
• A medium grain mortar: for
  create internal rustic plasters;
• A red grain mortar: for
  work on external plasters.

Plastering mortar: i
binders

Binding materials are used to give the
mortar its grip characteristics, therefore determining its resistance.

The most used binders are:

• Air lime;
• Plaster;
• Cement;
• Hydraulic lime.
