Compression Test on Concrete

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. The most common age at testing is 28 days, but tests can be made at 1, 3, 7 & 14 days also.
