Concrete Testing | SOCOTEC UK
Concrete is usually tested after seven and twenty-eight days of curing, as concrete will virtually reach its expected final strength in twenty-eight days. After seven days, it will usually give two-thirds of its 28 day strength, serving as a good early indicator of its final strength. Two to three cubes are usually taken in order to measure the

Compressive Strength of Concrete -Cube Test, Procedure, Results
The compressive strength of the concrete cube test provides an idea about all the characteristics of concrete. By this single test one judge that whether Concreting has been done properly or not. Concrete compressive strength for general construction varies from 15 MPa (2200 psi) to 30 MPa (4400 psi) and higher in commercial and industrial structures.

DOE Methods of Concrete Mix Design | Concrete Technology
The DOE method was first published in 1975 and revised in 1988. The DOE method of mix design is applicable to all types of concrete mixes including roads, while Road Note No. 4 was applicable to roads and air fields only. This method can also be used for concrete containing fly ash. DOE method is a standard method of mix design in U.K. now.

Concrete Strength Testing Methods
For new constructions, you can pour concrete cylinders or cube samples and cure them, or for existing structures, you can extract core samples. Thereafter you destructively crush-test a series of those samples in a testing machine. Using statistical methods, you can then determine the characteristic strength of the concrete.
