Dry mortar refers to pre-mixed masonry materials composed of cement, sand, and additives stored in bags and mixed with water before use. There are two main types of dry mortar: ordinary dry mortar and special dry mortar.
What is ordinary dry mortar?
Ordinary dry mortar is a mixture of cement, sand, and water, with or without adding lime; the ratio of ingredients in ordinary dry mortar varies depending on the specific application. Ordinary dry mortar is used for general construction purposes such as masonry and plastering; its primary goal is to provide a strong and stable bonding agent between bricks or blocks and to fill the gaps between them.
What is special dry mortar?
Special mortar has different materials and additives, such as polymers, fibers, and aggregates. These additives give the mortar unique properties and characteristics that allow it to perform specific functions. For example, additives like lightweight aggregates may be added to thermal insulation mortar to improve its insulating properties. There are also plastering mortar, tile adhesive mortar, self-leveling mortar, hot melt coating, etc., all special mortars.
Application of ordinary dry mortar
Ordinary dry mortar is widely used to construct masonry walls for residential and commercial buildings, such as brick, blocks, and stone. It binds the materials and provides structural strength to the wall. There are three main types of ordinary dry mortar:
1. Masonry mortar: Player bricks and blocks in masonry walls.
2. Stucco mortar: Used for exterior and interior plastering.
3. Tile adhesive: Used for laying floor and wall tiles.
Application of special dry mortar
Special dry mortar is specifically formulated to meet specific construction needs such as thermal insulation, soundproofing, waterproofing, and self-leveling. It may contain different ingredients, such as lightweight aggregates, fire retardants, or high-performance additives, to achieve the desired properties.
For example, thermal insulation mortar is used for building exterior wall insulation, which can reduce heat loss and improve building energy efficiency. Decorative mortar is used for exterior and interior decoration, adding color and texture to the building surface. Self-leveling mortar is used to create flat and smooth floors or surfaces. Waterproof mortar is used where water is likely to penetrate and cause damage.
Conclusion
In addition to the materials and additives used in special mortar, the mixing and application methods may differ from those used for ordinary mortar. Some special mortars may require special mixing equipment or application techniques to achieve the desired performance. Special mortars are typically more expensive than ordinary mortars due to their unique formulation.
Overall, while the ordinary dry mortar is used for general construction purposes, special dry mortar is designed to meet specific construction needs and may include different combinations of ingredients to achieve desired properties.
