As per the British standards, concrete is capable of carrying a strain up to 0.0035 and steel starts yielding at a strain of 0.002 and it can increase greater than the concrete. When the axial stress exceeds a certain amount resulting in concrete strain grater than 0.0035 concrete will fail suddenly. It will be a sudden crushing of concrete.

Compressive Strength Test Idea: 1- Concrete is poured in the mould and compacted properly to reduce the amount of voids. 2- After 24 hours, moulds are removed and test specimens are then placed in water for curing. 3- After the specified curing period [3, 7, 28, 56, or 91 days], specimens are tested by the compression testing machine.

Aggregate Crushing Value (ACV) The aggregate Impact value gives a relative measure of the resistance of an aggregate to sudden shock or impact, which in some aggregates differs from its resistance to a slowly applied compressive load. With aggregate of aggregate impact value higher than 30 the result may be anomalous.

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

Specific gravity and Water Absorption Test of Aggregates are major important tests to be performed on aggregate. These two parameters or properties of aggregate play an important role in the mix design of concrete. As we know that aggregate occupies 70 to 80% volume of concrete, its testing becomes essential before use.

Make sure the fresh concrete is mixed frequently. 3. Make sure the weighing is set to zero. (Ashikin Mastura 23859) By carrying out this experiment, we were able to determine the production of concrete mixing. the first step into making the concrete is batching of materials.

So we generally don''t depend on concrete in tension, and cracking is not considered ''failing''. Crushing, on the other hand, does amount to failure. In bending elements, we want the ultimate failure mechanism to be yielding of steel rather than crushing of concrete, as that is a much more ductile failure mode.
