IMPORTANT TESTS ON BRICKS YOU SHOULD KNOW
Bricks are one of the most important construction materials used in the building industry. They are used in various applications, from building walls to paving roads. However, not all bricks are created equal. Some may have defects that can compromise their strength and durability, leading to potentially dangerous situations.
To ensure that bricks are of good quality, various tests are conducted on them. In this article, we’ll discuss some of the important tests on bricks you should know about.
1. Compression test: This is one of the most common tests conducted on bricks. In this test, a brick is placed between two plates and pressure is applied until it breaks. The amount of pressure required to break the brick is recorded, and this gives an indication of the brick’s compressive strength.
2. Water absorption test: This test determines the amount of water a brick can absorb. In this test, the weight of a dry brick is recorded, and then the brick is immersed in water for a specified period of time. After the specified time, the brick is removed from the water, and its weight is recorded again. The difference between the weight before and after immersion gives an indication of the brick’s water absorption capacity.
3. Efflorescence test: This test is used to determine the presence of salts in bricks. When bricks are exposed to water, the salts present in them can dissolve and move to the surface of the brick. When the water evaporates, the salts can form a white powdery deposit on the surface of the brick. This deposit is called efflorescence. The presence of efflorescence indicates the presence of salts in the brick, which can affect its strength and durability.
4. Hardness test: This test is used to determine the hardness of a brick. In this test, a small metal ball is pressed against the surface of the brick, and the depth of the indentation is measured. The depth of the indentation gives an indication of the hardness of the brick.
5. Soundness test: This test is used to determine the ability of a brick to withstand the effects of weathering. In this test, a brick is immersed in water for 24 hours, and then it is dried in a well-ventilated area for 24 hours. This process is repeated five times. After the fifth cycle, the brick is examined for any signs of cracking or disintegration.
In conclusion, conducting these tests on bricks is important to ensure that they are of good quality and suitable for use in construction. It is recommended that these tests be conducted by a qualified professional to ensure accurate results. By taking these precautions, you can ensure that the bricks used in your building project will be strong and durable, providing a safe and reliable structure for years to come.
