The test sample in the core drill is a hard concrete test (ASTM C-39) method by taking samples of concrete cylinders from areas of compressive strength is doubtful. Sampling is done by drill tool which drill is in the form of “pipe” from diamond, so that the concrete sample is obtained in the form of cylinder. Building made of concrete construction, it must be required corresponding the required strength through planning determined by testing the quality of concrete on the job mix SNI test standard, but in the process of concreting that does not be corresponding the method and the conditions that must be obeyed often results in strength the concrete construction that has been built does not achieve the desired strength. When the existing concrete building strength checks are carried out, it is necessary to evaluate how much the error or the difference in the results of the test on the concrete quality of the planning and quality of hard concrete that is ready to be built. For this reason, one of the hard concrete strength tests is done by using the core drill method.
