Determination of high-strength concrete strength by method of separation and chipping
In the article, in particular, is pointed out that modern high-strength concretes and technology of stacking differ from concrete, for which in GOST 22690-88 provides universal calibration according to the method of separation of chipping. New anchors and devices with effort of digging to 100 kN have appeared on the market. In this regard, there is the question of admissibility of universal calibration curves application for monitoring the strength of high-strength concrete classes B60- B80
