• ### Compression Test on Concrete Building Research Institute ...

The cube is demoulded just before testing at 24 hours. For greater ages at test, demoulding takes place between 16 to 28 hours after adding water in a concrete mix and the specimens are stored in a curing tank at 18 0 C to 22 0 C until the required age.

• ### Cube test REPORT DCC2042 SlideShare

Dec 19, 2015· Cube test REPORT DCC2042 1. This test measures the uniaxial compressive strength of concrete cubes which are made, cured and tested to very specific requirements. It does not measure or predict in any unique way the strength of the concrete in the structure.

• ### Concrete Testing | Cube Testing Services

Cube concrete testing can take place at 7, 14 and 28 days to verify the compressive strength of the concrete. Please note that we would have to be notified upon booking that you wish for testing to take place. Cube concrete test results will follow post the 28 day compressive test .

• ### Concrete Testing Information The Concrete Network

Testing Concrete. You should take concrete testing seriously and start off on the right foot by securing the services of a certified testing laboratory (see ASTM C 1077) employing field and lab technicians that are ACIcertified. This will give you the greatest assurance that proper sampling and proper field and laboratory tests are conducted.
