CRACK RESISTANCE AND STRENGTH OF CONCRETE UNDER TENSION AFTER PRELIMINARY COMPRESSION BASED ON ITS STRUCTURAL THEORY
The results of theoretical researches on the basis of the structural theory of crack resistance and tensile strength of concrete after preliminary long compression of various intensity are stated. For the structural scheme in the form of a checkerboard arrangement of the aggregate in the cement matrix, the stress-strain state of concrete during unloading or subsequent stretching to stresses when the cement stone has exhausted its bearing capacity (cracks are formed) and destruction of concrete as a whole is considered.Analytical dependences of definition of the specified parameters for various levels of precompression are resulted.
