How do we test BRICKS
How do we test Flyash/Cement/Concrete bricks?
Compressive Strength Test
Usually when we compare Clay bricks with Fly ash bricks the compressive strength is always 3 times higher in the Fly ash bricks. The minimum compressive strength of clay brick is 3.5 N/mm² and the Fly ash bricks shows a strength of 10-12 N/mm². Bricks that are used in constructions should have these minimum compression strengths without which they do not qualify to be used. The brick testing machine is used to test the compressive strengths
Water Absorbtion Test
When we dip the Fly ash brick in water it should not absorb water more than 15%. To test the same we should first choose the bricks and the tested brick should be first dried in an over with a temperature of around 115 degrees Celsius and weight should be recorded. Once this is done we need to dip the brick in water and for one day and the water temperature to be maintained at around 25 degrees Celsius. The brick has to be removed after a day and immediately weighed to see the total percentage of water it absorbed.
In order to test this we will have to first choose a warm and well ventilated room below 30 degrees Celsius. Choose a dish and vertically immerse one end of the brick into water and the immersion depth should be 2.5cm. The brick starts absorbing the water and the left over water evaporates. Once this is done again place same amount of water in the dish and allow it to absorb and evaporate as done before. Once this is done we will have to look for white spots on the bricks surface and if the difference is observed sue to salt deposits then we call the brick as efflorescence.
Shubham Bricks Quality
It is not very common for manufacturers to check bricks quality. Many people determined by looking at the surface of the bricks but this is not the right way to do it. One of the key criteria that has to be tested is the compressive strength which can be done only through a brick testing machine. We have installed a brick testing machine in the plant where anyone can come and test the bricks compression strength. We at Shubham Bricks also allow people to bring other suppliers bricks and test it free of cost. This way the consumer can be sure of the brick quality and take home a premier Fly ash brick that lasts for generations to come.
