crushing value for ordinary concrete Tests on concrete may 2001 page 95 92 crushing strength of concrete 921 introduction crushing tests are universally used for determining the strength of concrete and the standard test measures the crushing strength at an age of 28 days after mixing because of the time delay in obtaining the test results for concrete crushing strength
The Edge Crush Test or ECT is a newer test developed to look specifically at how much force a corrugated material can withstand on its edges without crushing Instead of applying force to the face of the corrugated material as the Mullen Burst Test does ECT applies force to the edge The material is compressed top to bottom until it buckles.
This value is approximately 15 lesser than the ultimate strength The strain at which crushing of concrete takes place is 0.0025 for high strength concretes to more than 0.0045 for low strength concretes For design a conservative value of 0.003 is considered as the ultimate strain for all concretes except very high strength ones.
