WHY is Compressive Strength Determined? Compressive strength test results are primarily used to determine that the concrete mixture as delivered meets the requirements of the specified strength, c, in the job specification.

Why Perform a Compression Test? ... Compressive stress and strain are calculated and plotted as a stress-strain diagram which is used to determine elastic limit, proportional limit, yield point, yield strength and, for some materials, compressive strength.

Because the voltage supplied must be gradually increased to the test voltage value at a low speed, the test speed of conventional DC compressive strength test apparatus is slow.

The study considered four test methods and the influence of the variables, height-breadth ratio, and mix proportions on the compressive strength values given by those test methods. The tests were designed to determine the reproducibility and repeatability of each test method, as well as to facilitate statistical analysis.
