2020417 Compressive strength of concrete depends on many factors such as watercement ratio, cement strength, quality of concrete material, quality control during the production of concrete, etc. Test for compressive strength is carried out either on a cube or cylinder. Various standard codes recommend a concrete cylinder or concrete cube as the standard specimen for the test.

201533 In normal strength concrete, the micro cracks form when the compressive stress reaches until 40% of the strength. The cracks interconnect when the stress reaches 8090% of the strength. The fracture surface in NSC is rough. The fracture develops along the transition zone between the matrix and aggregates. Fewer aggregate particles are broken. Marcio (2002)
