    First of all Concrete Compression Testing Machines or probably better know as a Cube Press seems like a old technology. Protsurv provides a complete selection of concrete testing equipment, Rebar Locators, Concrete Test Hammers, Cube Moulds & Slump Cones,and even more for fresh and in-place concrete structures in accordance with SANS, TMH1 and other standards.After 14 days of casting concrete, concrete gains only 9% in next 14 days. So, rate of gain of strength decreases. We have no clear idea upto when the concrete gains the strength, 1 year or 2 year, but it is assumed that concrete may gain its final strength after 1 year.So, since the concrete strength is 99% at 28 days, it's almost close to its final strength, thus we rely upon the results of ...

    Mar 29, 2020 Compressive strength of concrete cube test is the most important strength test for concrete. This single test gives an idea about all the characteristics of concrete. Concrete are very strong in compression. It is assumed that whole of the compression will be taken up by the concrete at the time designing any RCC structure.So, 100mmx100mmx100mm concrete cubes are used in place of 150mmx150mmx150mm cubes to raise the used stress to crush the concrete cubes. For normal concrete strength, the cube size of 150mmx150mmx150mm is already sufficient for the crushing strength of the machine. Cube Test: Instrument And Material.

Why do we test at 7, 14 & 28 days? Concrete is a macro content with Sand, Cement, & Coarse aggregate as its micro-ingredient (Mix Ratio) and gains its 100% strength over time at the hardened state.

  • Concrete cube crush test

    Concrete cube crush test

    Concrete cube testing or cylinder testing is done to check the development of the strength of the concrete. In other words, we test the concrete to check whether it has reached or developed beyond the characteristic strength of concrete assume in the design. Based on the test results, conformity can be checked as per the relevant standards.After that crushing is done in the usual way. The cube can be tested after 3, 7, 14 and 28 days. Cube is placed in compression testing machine and axial load is applied at the rate of 140 kg/ cm2. In actual concrete is required sufficient time to gain strength. Usually 28 days strength is considered as the full strength of concrete.
