What is Lefton brick and how is it produced?
Fully controlled production process, uniform color, suitable resistance and standard porosity are the most important features of Lefton brick. In new productions such as Momtaz Alavi's fully automatic brick, the accuracy of the machinery has made human errors to be eliminated and the quality of the product to be more uniform and stronger.
Technical specifications of Lefton brick
Standard dimensions
- Length about 23 cm
- Width 10 to 11 cm
- Height 5 to 7 cm
Controlled weight
Good compressive strength
Standard water absorption
The amount of water absorption in Lefton brick should be controlled based on the national standard to prevent dandruff and weak joints.
Advantages of Lefton brick in construction
Using Lefton brick provides many important benefits for the project. Some of the most important advantages are:
High execution speed
The presence of holes makes the mortar penetrate better into the brick and increases the speed of installation. This reduces the cost and time of the project.
Reducing the dead load of the building
Due to the perforated structure, Lefton brick is lighter than pressed bricks and therefore reduces the dead load of the structure.
Excellent mortar adhesion
Appropriate surface and standard holes help the mortar to fully penetrate the brick and create a stronger connection.
Durability and long life
It is resistant to heat, cold, humidity and environmental conditions and it maintains its quality well over the years.
Easy implementation by inexperienced personnel
Using Lefton brick is not particularly complicated and this is one of the reasons for its popularity in small and large projects.
Different types of Lefton bricks
Lefton brick is produced in several main types, each of which has a specific use:
Lefton brick with 5 holes
Lighter weight and use in non-load bearing walls.
Lefton brick with 7 holes
The most widely used type; Suitable for all types of wall coverings.
Lefton brick with 10 holes
Lighter weight and very high execution speed.
New products such as Mammoth Alavi fully automatic brick provide all these models with strict quality control.
In what parts of the building are Lefton bricks used?
The applications of Lefton brick are very wide and are used in various construction sectors. The most important things:
Perimeter walls
It is an excellent choice for external walls due to its suitable dimensions and sufficient strength.
Internal porcelain blade
The appropriate weight has made it an ideal option for cutting blades.
Semi-bearing walls
In many projects, Lefton brick is used as a material for semi-load-bearing walls.
Building sheds and warehouses
Due to the speed of implementation and good resistance, it is also used in the construction of shed walls.
Residential and office buildings
For beauty, uniformity and long-term durability, Lefton brick is a popular choice for professional builders.
Why is the quality of Lefton bricks so important?
If the lefton brick is not produced with high quality, problems such as cracking, scaling, failure during execution or excessive water absorption will occur. All these things can reduce the durability of the project years later.
For this reason, Mumtaz Alavi's fully automatic brick products have become one of the main options of professional contractors in recent years, as they guarantee uniformity of dimensions, high strength and strict quality control.
The role of Mamoz Alavi fully automatic brick in improving the quality of Lefton bricks
Fully automatic technology has brought great advantages to Lefton brick production, including:
Complete uniformity of dimensions
Accurate dimensions increase the speed of wall construction and minimize the amount of material waste.
Higher resistance
Scientific control of the baking process makes the Lefton brick produced by this group to be at a higher level in terms of pressure resistance.
Controlled water absorption
This feature prevents dandruff and weak adhesion.
uniform color
One of the important factors of the beauty of the project and preventing uneven stains.
Standard packaging
Healthier transportation, reducing breakage and increasing the speed of unloading materials in the workshop.
All these features have made Mumtaz Alavi fully automatic brick the first choice of many builders in luxury projects, residential complexes, sheds and large buildings.
How to choose the right Lefton brick for your project?
To choose the best Lefton brick, you need to check some key points:
1. Checking the uniformity of color and dimensions
Bricks must be completely uniform; This issue affects the facade, wall covering and mortar consumption.
2. Compressive strength control
Lefton brick must have passed standard resistance tests.
3. Adequate water absorption
Neither more nor less than standard.
4. Industrial construction
Industrial products such as Momtaz Alavi's fully automatic brick have higher quality due to the elimination of human errors.
5. Attention to the type of project
Load-bearing wall, non-load-bearing, inner blade or outer wall?
According to the need, the type of 5, 7 or 10 holes is selected.
Important points in implementing a wall with Lefton bricks
For the optimal use of Lefton brick, it is necessary to observe several points:
- Using mortar with the right quality and concentration
- Controlling the plumb line and accurate veining
- Proper filling of holes when constructing semi-load-bearing walls
- Depoting and maintaining bricks properly to prevent breakage
