 What exactly are Porotherm Bricks? Characteristics, Benefits, and Applications

Porotherm clay bricks are perforated clay bricks that can be perforated horizontally or vertically. They are made from natural clay, coal ash, rice husk, and granite slurry and come in a variety of sizes (the most common being 400x200x200 mm). Because of the desired thermal insulation properties, this type of brick is referred to as a porotherm.

The perforation of the clay brick creates an exceptional walling system that aids thermal insulation, resulting in cooler interiors in hot seasons and warm interiors in cold seasons.

The porotherm clay bricks are simple to use, inexpensive, and environmentally friendly, and they can be used to build both non-load bearing and load bearing walls. The porotherm bricks are light in weight, durable, strong, and fire resistant. It is suitable for use with dry mortar, eliminating the need for curing time.

Porotherm Brick Properties

1. The compressive strength exceeds 3.5 MPa.
2. Excellent thermal and acoustic insulation.
3. It is 60 percent lighter than a traditional solid concrete block.
4. Fire resistance is excellent.
5. The density ranges between 694 and 783 kg/m3.
6. The combination of large size and light weight results in a low dead load.
7. Water absorption is approximately 15 percent.

The Benefits of Porotherm Bricks

1. Good physical strength

Porotherm brick has a compressive strength greater than 3.5MPa. The use of high temperatures during the manufacturing process, as well as the presence of teeracotta material in its composition, give the material exceptional strength.

2. Thermoelectric Insulation

Because of the perforation of the bricks, porotherm bricks have excellent thermal insulation.

3. Long-lasting

Porotherm bricks are highly durable and have a long life span due to their high compressive strength, fire resistance, and resistance to carbonation. Water absorption is around 15%, so the risk of dampness, cracks, or shrinkage of walls is extremely low.

4. inexpensive

The porotherm bricks not only save a lot of energy, but they also reduce construction and operation costs. The use of this type of brick would eliminate the need for air conditioning in the summer and heaters in the winter, saving energy. It eliminates the need for sand and cement in wall construction, lowering construction costs. Finally, it requires no upkeep.

5. Environmentally Conscious

The porotherm bricks contain recycled materials. Because no chemical materials are used in its formulation, it will not cause allergic reactions.

6. Construction Speed

When porotherm bricks are used, the speed of wall construction increases significantly. This is due to the lightweight nature of the brick, its ease of handling, and the elimination of curing time, as sand and cement are not required for the construction of porotherm brick walls.

Furthermore, it is easy to cut and chisel, making fixture installation much easier. Finally, porotherm ensures a clean and dry work site, so there is no debris to be disposed of.

Porotherm Bricks' Drawbacks

1. Because of their density of 694 to 783 kg/m3, porotherm clay bricks cannot be used in the construction of large structures.
2. It may be vulnerable to salt attacks due to its 15% water absorption, and thus the structure's strength will be reduced.
3. Porotherm bricks cannot be used for foundation and base-slab work in areas with a high ground water table. This is due to the fact that such bricks might not be able to withstand the negative pressure of water and capillary action.

Porotherm Brick Applications

• Load bearing and non-load bearing wall constructions are available.
• The partition wall
• Within framed structures, infill panels are used.
• Internal and external walls that are single leaf or monolithic.
• The inner leaf of cavity walls with brick faces.
• Rendering cavity walls' inner and outer leaves.
