Bricks are the most commonly used material for building homes, and it’s been used for centuries because of high compressive strength.

Bricks comprise an important aspect for building different various structural elements such as bridges, tunnels, archways, sidewalks, patios, walls, floors, and many more.

Moreover, bricks are also favourable because of their aesthetic appeal and visually interesting looks.

However, over the years, engineering bricks are used to build homes along with different building structures. The reason for this is that engineered bricks comprise high compressive strength along with being low porous in nature.

The role of engineering bricks comes into play in buildings that are weak in resistance to frost, water, and to increase overall strength.

What are the Engineering Bricks?

Engineering bricks are comprised of high strength along with having low porosity in nature. Engineering bricks are used in constructions that need resistance from external elements such as water, frost, and dampness.

Additionally, engineering bricks can be further classified into Class A and Class B bricks. Class A engineering bricks are normally blue in colour because of the high firing temperature. Moreover, Class A engineering bricks contain a strength of 125 N/mm2 (18,100 lbf/sq in) and porosity of less than 4.5%.

Class B engineering bricks contain physical strength of 75 N/mm2 (10,900 lbf/sq in) along with water absorption levels of less than 7%.

Main Types of Engineering Bricks

• First Class – These types of engineering bricks are of the highest quality, and they are burnt for making the surface even and smooth. Moreover, these types of engineering bricks are reddish in colour and it is perfectly rectangular in shape. Since these bricks are of the highest quality, therefore it should not produce any fingermark when scratched. They should produce a metalling sound when it is struck with another first-class engineering brick.
• Second Class – Second class of engineering bricks is over-burnt during manufacturing. These over-burning results in giving an uneven shape that is not perfectly rectangle. Second-class bricks have a solid surface similar to that of first-class bricks. Second-class bricks also have a uniform solid colour and should produce a metalling sound when struck with another second-class brick. Moreover, second class bricks should have a water absorption level of 22% with compressive strength of 70 kg /cm2
• Third Class – Third class bricks are not properly burnt as in the case of first-class or second class bricks. Additionally, these contain irregularity in shape and the colour of these bricks is slight reddish along with few yellow spots.

Conclusion

You will find different types of engineering bricks that are used by architects, civil engineers, and builders.

Since they are available in all shapes and sizes, we would recommend you to carry out extensive research.

We would also hope that this article helped you to make progress in building your dream home.
