What are the brick grades?

There are three grades of brick to choose from:

Severe Weathering (SW): Able to experience freeze and thaw cycles; perfect for cold climates.
Moderate Weathering (MW): Tolerance to frost and freezing; used for outdoor walls.
No Weathering (NW): For indoor use only.

What is a class brick?

Clay bricks are classified as first class, second class, third class and fourth class based on their physical and mechanical properties. First Class Bricks. 1. These are thoroughly burnt and are of deep red, cherry or copper colour.

What are the three brick classifications?

What are the different types of bricks?

Sun-dried bricks. Also known as unburnt bricks, these types of bricks are mostly used for decorative purposes because they are the weakest.
Burnt bricks. These bricks are divided into four categories:
Concrete bricks.
Lime bricks.
Engineering bricks.
Fly ash bricks.

What is a Type 1 brick?

First class bricks are good quality bricks compared to other classes. They are molded by table-molding and burnt in large kilns. So, these bricks contain standard shape, sharp edges and smooth surfaces. They are more durable and having more strength. They can be used for permanent structures.

What are 4th class bricks?

Fourth class bricks have poor quality and not used for construction. These bricks are crushed and used as aggregates for making of concrete. The bricks which are over-burnt and due to this these bricks are brittle. These bricks are easily breakable and not suitable for construction.

What are AAC bricks?

Autoclaved aerated concrete (AAC) is made with fine aggregates, cement, and an expansion agent that causes the fresh mixture to rise like bread dough. In fact, this type of concrete contains 80 percent air. In the factory where it is made, the material is molded and cut into precisely dimensioned units.

What is CLC brick?

Cellular Light Weight Concrete Bricks/ Blocks (CLC) is also called as Foam Concrete Blocks. Advantages: Light in Weight : CLC blocks are very lightweight with density ranging from 300 to 1800 Kg/m3. Three times less weight then clay or fly ash brocks. Eco friendly : CLC blocks are Environment-friendly.

What is AAC and CLC blocks?

AAC blocks are lightweight building blocks. They are cut into masonry blocks or made into larger planks and panels. CLC is called Cellular Light Weight blocks Concrete and it is also called as Foam Concrete.

Which is best AAC blocks or CLC blocks?

1, the compressive strength of AAC block are better than the other two concrete blocks (CLC, Fly ash based concrete).

What are CLC bricks?

Is CLC block load bearing?

CLC Bricks Are Available in 3 Grade Strengths: Grade A: These are used as load bearing units & have a brick density in the range of 1,200 Kg/Cum – 1,800 Kg/Cum. Grade B: These are used as non-Load bearing units & have a brick density in the range of 700 – 1,000 Kg/Cum.

What is the difference between first class and second class bricks?

Like first class bricks, second class bricks are also hard and well burnt but may have somewhat irregular in shape or size and may have slight irregularities in surface. Other qualities are the same as those of first class.

What are the standards for model buildings made of bricks?

All the model buildings in the United States refer ASTM standards for bricks. In similar to that of ASTM, Canadian Standards Association (CSA) has also prepared codes for fired Masonry Bricks made from clay or shale.
