3.3 Considerable care must be used to compare the results of different determinations of the cold crushing strength or modulus of rupture. The specimen size and shape, the nature of the specimen faces (that is, as-formed, sawed, or ground), the orientation of those faces during testing, the loading geometry, and the rate of load application, may all significantly affect the
The Cold Crushing Strength (CCS) represents the ability of a product to resist failure under compressive load at room temperature. It has an indirect relevance to refractory performance, and is used as one of the indicators of abrasion resistance. The higher the CCS of a material is the greater should be the resistance to abrasion. Refractories with high CCS are also

Oct 28, 2013 Specified concrete compressive strength is the minimum compressive strength at which the concrete should fail in standard tests of 28-day-old concrete cylinders. A typical concrete compressive strength specification requires 4,000 to 5,000 psi at 28 days.

Crushing Concrete Cube Or Cylinder At 28 Days. Apr 01 2018nbsp018332the 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
Load is applied at a uniform rate of 4 tonnes. Release the load; Take the aggregate out of cylinder and sieve them through 2.36 mm IS sieve. Weight this fraction passing through it to an accuracy of 0.1 gm. This fraction is a quantity of loss of material due to crushing.
and a constant load is applied to the cylinder until it breaks. The compressive strength is calculated based on the applied load and the size of the test cylinder. It is important to center the cylinder between the loading plates and to apply the load at a constant rate. Loading rates, sample alignment and capping procedures can affect the results.
The specimen so placed in the compression testing machine is loaded in the rate of 14 N/mm 2 per minute. The crushing load is noted. Then crushing strength is equal to this crushing load divided by the area where the load is applied. At least three specimens must be tested, and the average ought to be taken as crushing strength.
