What are the characteristics of bricks?

They should be sound and compact. They should be free from cracks and other flaws such as air bubbles, stone nodules etc. with sharp and square edges. Bricks should not absorb more than ¹⁄₅ of their own weight of water when immersed in water for 24 hours (15% to 20% of dry weight).

What is first and second class brick?

They are two Types: Type A brick and Type B brick. The Type A brick has a minimum compressive strength of 125 N/mm2 and maximum water absorption of 4.5%. The Type B brick has a minimum compressive strength of 75 N/mm2 and maximum water absorption of 7%. Type B bricks are used widely.

What are the 4 types of bricks?

What are the different types of bricks?

What is the size of brick?

Standard bricks

The standard co-ordinating size for brickwork is 225 mm x 112.5 mm x 75 mm (length x depth x height). This includes 10 mm mortar joints, and so the standard size for a brick itself is 215 mm x 102.5 mm x 65 mm (length x depth x height).

What is the size of first class brick?

First class brick work is made by using first class bricks and cement mortar. This brick work is used for load bearing walls. It is made in rich mortar in which the cement and sand ratio is from 1:3 to 1: 6.

How many classes of bricks are there?

Based upon the physical and mechanical properties the bricks are classified into four types such as, first class, second class, third class and fourth class.

Is bricks a code classification?

Each class of bricks is further subdivided into two sub-classes A and B based on tolerances and shapes e.g. brick of classification 100 is further sub-classified as 100A and 100B and so on.
