A concrete cube test involves taking a sample of freshly mixed concrete, letting it cure, then crushing it and measuring its compressive strength. Many concrete suppliers carry out this process at a certified test house, away from their facilities. At Rapid Readymix, we conduct all our cube tests in-house, as we have a state-of-the-art testing

Concrete cubes are crushed and tested. Once cured and ready to test, each cube is placed into our concrete crusher, which steadily exerts force on the cube until it breaks. The rate at which the cube crushes is measured, and this gives us its compressive strength. Read our article to learn more about how cube testing works.

Concrete Compression Testing. Concrete strength is measured by crushing concrete cubes or cylinders to failure and recording this strength. VJ Tech designs and manufactures Automatic and Semi-Automatic Concrete Compression Testing Equipment with loading capacities for either 2000 kPa or 3000 kPa, together with all acccessories required.

Concrete elements are designed on the basis of a 28-day cube’s crushing strength. A 28-day cube’s strength actually represents the characteristic strength of the concrete. It is mandatory to test the concrete cubes or cylinders at the age of 28 days as per almost all building code requirements. Now, once your 7-day test and even your 14-day

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

Like the cylinder break test, the concrete cube test is performed for the purpose of determining the compressive strength of a concrete element. The cubes used for this test have a dimension of 150 x 150 x 150 mm as long as the largest aggregate does not exceed 20 mm. Generally speaking, the cubes are cured for and tested at 7 and 28 days

Concrete cube test Procedure. Firstly, in a clean and dry pan, fine and coarse aggregates is taken by weight. The quantity of material taken should be enough to prepare at least 3 cubes of 150mm in size. It would be better if well-graded aggregates are used. In general, clean and dry aggregate passing 20mm sieve size is used for coarse

Cube Testing. The cubes are generally tested at 7 & 28 days unless specific early tests are required, for example to remove a concrete shutter safely prior to 7 days. Usually 1 cube will be tested at 7 days and 2 cubes at 28 days, however this may vary depending of the requirements, check the design first.

Concrete cubes may get crushed on one side or will develop tensile crack on one or more faces and fail. Fig shown below shows some of the likely unusual failures of concrete cubes. This type of failure will give lower indication of compressive strength of concrete. These are usually due to defects associated with testing machine.
