3. Over Burnt or Jhama Bricks

types of bricks
Over Burnt Bricks

jhama bricks is also known as the vitrified brick as it is fired at high temperatures and for a longer period of time than conventional bricks. As a result, the shape is distorted. The absorption capacity is high.

The strength is higher or equivalent or first-class bricks. These bricks are used as lime concrete for the foundation concrete. It is also used as a coarse aggregate in the concrete slab.

4. Extruded Brick

types of bricks
Extruded Brick

It is made by mixing water and clay in a steel die, with a very regular shape and size, then cutting the resulting column into shorter units with wires before firing. It is used in construction with limited budgets. It has three or four holes constituting up to 20% volume of the brick.

5. Molded Brick

It is shaped in molds by hand rather being in the machine. Molded bricks between 50-65 mm are available instantly. Other size and shapes are available in 6-8 weeks after the order.

It is obtained by pressing the clay in molds and fried and fired & dried in kilns. It is the most used bricks. It requires plastering when used in construction works.

8. Fly Ash Clay Brick

It is manufactured when fly ash and clay are molded in 1000 C. It contains a high volume of calcium oxide in fly ash. That is why usually described as self-cementing. It usually expands when coming into contact with moisture. It is less porous than clay bricks. It proved a smooth surface so it doesn’t need plastering.

9. Concrete Brick

types of bricks
Concrete Bricks

These brick type is made of concrete. It is the least used brick. It has high compression strength and the quality of brick is high. These bricks are generally provided above and below the damp proof course.

These brick types are used can be used for facades and internal brickworks because of their sound reductions and heat resistance qualities. It is also called mortar brick. It can be of different colors if the pigment is added differently during the manufacturing of concrete.

10. Sand-lime Brick

Sand, fly ash and lime are mixed and molded under pressure. During wet mixing, a chemical reaction takes place to bond the mixtures.

Then they are placed in the molds. The color is greyish as it offers something of an aesthetic view. It gives a smoother finish and uniform appearance than clay bricks. It is used as a load-bearing member as it is very strong in crushing strength.

11. Fire Bricks

This brick types is also known as refractory bricks. It is manufactured from a specially designed earth. After burning, it can withstand very high temperatures without affecting its shape, size, and strength. It is used for the lining of chimneys and furnaces where the usual temperature is expected to be very high.
