C10, with a strength of 8 newtons, is designed for kerb backing and bedding. C40, our strongest concrete with a strength of 40 newtons, is designed to withstand heavy duty loads. Concrete Grading. We offer different grades of concrete to ...

  Compressive strength of concrete after early loading

  In modern construction projects it is necessary to work with concrete at a time before its strength can be fully developed. Applying large construction loads to a structure can lead to a reduction in strength if the serviceability limit has been exceeded. However, the effects of smaller compressive loading on concrete cubes, below the serviceability limit state, have been found to have a ...
