Corrosive influence of longitudinal cracks in the protective layer of concrete on the strength and stiffness of conventional concrete elements
According to the long-term and short-term experimental studies of conventional reinforced concrete elements under the action of central and eccentrically compressive loads obtained functional dependence of the change short stiffness and compressive strength of the averaged values and the maximum opening width corresponding to the length of longitudinal cracks in the protective layer of concrete. Quantitative changes in the value of hardness and strength, depending on the geometric parameters of corrosion of longitudinal cracks.
