Keep in mind that the standard level of strength for post-tensioning is 75% and in some cases, your concrete can reach this level of strength sooner than expected. By employing the maturity method, you’ll be able to closely monitor when your concrete reaches the necessary level of strength so you can move forward post-tensioning as soon as possible.

The crushing or compressive strength of normal building bricks should not be below 3.5 N/mm². The bricks of high quality should not have strength below 14 N/mm². The compressive strength test is also known as the crushing strength test which is an important type of laboratory test conducted on bricks to determine the load-carrying capacity of bricks when subjected to a compressive load.

The Crushing strength or compressive strength is given by the formula as: C= P/A. Where, C = compressive strength. P = Load at failure. A = cross-sectional area of bearing face of the specimen. Then the average value of the six specimens is calculated and the result is recorded for that stone sample. You may also like.

The crushing of concrete cubes or cylinder samples is required in a construction especially concrete structures. The reason why this is to verify the strength given in the design mix. Let say for example for a concrete column commonly it has 60 megapascals of specified strength. When you crush it, the result should be equal or more than 60 Mpa. The specified strength should be achieved at 28
