Experimental estimation of the parameters of crack progression in concrete
Abstract
This article presents the influence of the structure on the characteristics of the crack resistance of concrete. Due to ease of manufacture and testing of samples, the method of determining the results of the test KIC beams notched. Depending on the conditions of application of the load, the schemes were used to obtain the characteristics of the crack resistance of concrete in four-point bending, stretching, splitting. They allow to accurately determine stress coefficient KIC.
