6 Cubes of 150 x 150 x 150 mm size (the nominal size of aggregate does not exceed 38 mm) shall be cast, 3 for 7days testing and 3 for 28days testing. A set of 3 cubes (specimen) average strength will be a sample. The individual variation of a set of 3 cubes should not be more than ± 15% of the average.
EN 123904 refers to compression tests on cubes and cylinders, while EN 7721 on masonry units (blocks). Depending on the level of automation CONTROLS offer DIGIMAX 3 : a semiautomatic compression tester;
compressive strength of high strength concrete. We use cylinders and cubes of different sizes for performing stable stressstrain tests. The tests were performed at a single axial strain rate, 10¡6 s¡1. This value was kept constant throughout the experimental program. Our results show that the postpeak behavior of the cubes is

The three Target tests indicate that after 24 hours, the mean compressive strength of the cubes should be between 5000 psi (typical) and 7396 psi (Target test). The mean strength for the cubes and the cylinders after 24 hours for the FLNRO test is 6512psi and 6889psi respectively, fitting within the Target range.

It consists of applying a compressive axial load to molded cubes at a rate which is within a prescribed range until failure occurs. The compressive strength is calculated by dividing the maximum load attained during the test by the crosssectional area of the specimen. Apparatus Weights and weighing device. Tools and containers for mixing.
This test describes how cylindrical concrete test specimens are made. Cylinder sizes are usually 6 in. x 12 in. or the more common 4 in. x 8 in. The size is either specified in job requirements or based on personal preference. Curing techniques for test samples are important and the method chosen depends on the product and customer specifications.
