Different Types of Bricks Used in Construction

Bricks are rectangular units of uniform dimensions. Clay is used to making bricks. In construction, there are different types of brick. When stone is not accessible, bricks are commonly utilized as a substitute. Brick is a common building material made of clay and comes in rectangular shapes. Because of their inexpensive cost and long lifespan, they have remained popular since ancient times.

Different Types of Bricks Used In Construction:
A. Types of Bricks Based on Building Process:
1. Unburnt Bricks:
Fig 1 Burnt Bricks
Fig 1: Burnt Bricks

Unburned bricks, often known as sundried bricks, are the most basic type of brick. The name of the process for creating these bricks says it all. It is typically utilized in rural areas or temporary projects because it is not burned but rather dried in the sun for hardening. They are less durable, have lower fire and water resistance, and are best utilized for temporary structures in our types of bricks used in construction.

2. Burnt Bricks:

Fig 3: Jhama Bricks

Because it is burnt at a higher temperature and for a longer period than regular bricks, it is known as the vitrified brick. The shape is altered as a result. The absorption capacity is quite great. The strength is comparable to that of first-class bricks, if not greater. It’s used as a foundation’s lime concrete. It’s also a coarse aggregate in concrete slabs and beams that won’t be exposed to water.

B. Types of Bricks Based on Quality:
4. First Class Bricks:
Fig 4 First Class Bricks
Fig 4: First Class Bricks

The dimensions of the first-class bricks are standard. These bricks are uniformly yellow or red. It has a well-burned texture and a uniform shape. The absorption capacity is less than 10%, and the crushing strength is 280 kg/cm2 (mean), with 245 kg/cm2 being the maximum (minimum). There isn’t any efflorescence on it.
When struck by another similar brick or a hammer, it makes a metallic sound. If one tries to do so with a thumbnail, it’s difficult enough to resist any fingernail expression on the brick surface. There are no pebbles, gravels, or biological materials in it. It is commonly used – for creating coarse aggregates of concrete, in construction of long durability, and for a building exposed to a corrosive environment.

5. Second Class Brick:

Fig 5: Second Class Bricks

Second-class bricks are thoroughly burned, and when knocked together, they produce a clear ringing sound. Minor differences in shape, size, or color are acceptable. When soaked in water for 24 hours, it must have a compressive strength of at least 70 kg/cm2 and an absorption value of 22 percent. On shattered surfaces, a slight variance in structure is acceptable.

6. Third Class Brick:

Fig 6: Third Class Bricks

It is somewhat under-baked; slightly over-baked is acceptable. The absorption capacity is greater than 15% but less than 20%. The size and shape are unusual, and the color is a pale red–colored softness.
140 kg sq. cm is the crushing strength. It makes a dull or burnt sound when struck by another similar brick. It produces a fingernail expression when one tries to perform anything with the thumbnail. These bricks are not suitable for high-quality buildings.

C. Types of Bricks Based on Raw Materials:
7. Burnt Clay Brick:

Concrete bricks are made with cement, sand, coarse aggregates, and water as the main materials. You can make these bricks in whatever size you like. Concrete bricks have several advantages over clay bricks, including the ability to be made on-site, a lower amount of mortar required, and the potential to be constructed in various colors due to pigmentation during the manufacturing process. Concrete bricks are used to make masonry and framed buildings, facades, and fences, and they have a great aesthetic appearance.

9. Fly Ash Bricks:

It contains class C or class F fly ash, a by-product of burning coal mixed with water and then firing at 1000 degrees Celsius. Class C fly ash is the best among the bricks used in construction for pillars, foundations, and walls because of its high calcium oxide content. It’s also known as “self-cementing” brick. Fly ash bricks are high fire resistance and high-strength uniform sizes for better joint,

10. Sand-lime Brick:

These are chemically-set bricks, which mean the procedure is finished using heat and pressure to speed up the chemical reaction. Artists utilize them to spark their work because they offer a smooth texture, acoustic insulation, and good fire resistance. These bricks are one of the most often used varieties of bricks in India, and they are utilized in a variety of applications in the building industry. In artistic works, such as ornamental works in structures, sand-lime or calcium silicate bricks are utilized.

11. Fire Brick:

Refractory bricks are another name for it. It’s made out of a particularly created earth. It can withstand extremely high temperatures without losing its shape, size, or strength after being burned. It’s used to line chimneys and furnaces where the temperature is likely high.

D. Types of Bricks Based on Manufacturing Method:
12. Molded Brick:
Fig 12 Molded Bricks
Fig 12: Molded Bricks

Instead of being molded in a machine, it is formed by hand in molds. Molded bricks with a 50-65mm diameter are available right away. Other sizes and shapes will be available 6-8 weeks after the order has been placed.

13. Extruded Brick:

Fig 13: Extruded Bricks

It’s manufactured by combining water and clay in a steel die with a fairly consistent shape and size, then wires to cut the resulting column into smaller units before firing. It’s commonly employed in construction projects with tight budgets. These bricks have three or four holes that account for up to 20% of the brick’s volume.

14. Dry Pressed Brick:
