Different Bricks and quality testing methods


How to test good quality bricks!

Brick is one of the important materials in making pizza oven. There are various types of bricks but all types are not good or suitable for making pizza oven. Even bricks are classified depending on their composition and quality. It is better to use first class brick for making your pizza oven. If you use first class bricks, it will mean better longevity of your pizza oven. Now, it is a question how to test quality of bricks or how to find out first class bricks! It is not very difficult to test bricks quality. If you subject a brick to some tests as follow, you will able to check quality of bricks that it is first class or second class.

Absorption

At first weight of a dried brick is measured and recorded the data. Then brick is immersed completely in tape water for sixteen hours. After 16 hours weight of that brick is measured and difference in weight is calculated. Difference in weight means water absorbed by that brick. This amount should not be more than 20% of the original weight of dry brick if it first class brick. This test is simple and you should test your brick following the method.

Compressive or crushing strength

There are several local institutes which test compressive or crushing strength of brick by using compression testing machine. If there is any place where it is done, you can check your bricks. First class bricks will show crushing strength 14 Pa. Second class and third class bricks will show this value 7 to 13 Pa.

Hardness

Hardness test is very simple and you don’t need to go outside for it. Just you have to hold a brick by your one hand and then try to mark on the surface of brick using your finger nail. If there is no remarkable scratch, brick is definitely of high grade. If there is mark on surface, it means damp brick and you should avoid this brick in making pizza oven.

Amount of soluble salt

Sometimes, bricks contain salt as a component of soil. If brick contains salt, it will cause efflorescence on the brick surface. If you use bricks contain salt, efflorescence may be results on wall of pizza oven. So you have to check the salt content in bricks before using for pizza oven.

At first, you have to immerse a brick in water for a period of 24 hours. Then it dried in shade. If there is any white or grey deposit on surface, it will indicate the presence of soluble salt. If grey or white deposit covers 10% of the surface, brick is second class. Again, this deposit more than 10% to 50% indicates low quality of the bricks. First class brick does not contain any salt. So if there is no grey or white deposit on brick surface, it is definitely first class brick.

Size and shape

There is a definite specification of brick. Quality bricks mean appropriate size and shape. Brick should be inspected closely for this test and brick will be rectangular with its sharp edge. Standard size of brick will be 190 mm × 90 mm × 90 mm (length × width × height).

Structure

By breaking a brick structure is examined. First class brick will be compact, homogeneous and free from defect like lumps, holes and the like.
