  • How to determine compressive strength of concrete?
    In this study crushing strength of concrete cubes is the usual destructive test to determine the compressive strength of concrete. The rebound hammer test, ultrasonic pulse velocity and core test are the non destructive tests to determine compressive strength of concrete and to obtain correlation between them.

    Is there a relationship between in-situ hardened concrete and cube crushing strength?
    Dr. Isam H, et al obtained unified relationship between the results of in-situ hardened concrete and the results of cube crushing strength of concrete by using statistical methods carried on concrete cubes with different mixing ratio and different curing conditions and finding core relation curves to predict the strength of concrete much better.

    Should concrete strength be measured using cores?
    According to national instructions, concrete strength should be measured using cores in every condition survey. 6 Thus, it is important that the results of the core tests lead to the correct conclusions on the compressive strength and in some cases even on the conformity of concrete.

    What is concrete crushing after yielding of steel reinforcement?
    Concrete crushing after yielding of steel reinforcement represents an under-reinforced member, which is typical of current reinforced concrete design standards. This failure mode ensures that a high level of member ductility is maintained prior to failure, thus providing ample warning before collapse.
