Application of Non-Destructive Methods for Quality Control of Concrete Repair Efficiency

Abstract

abstractEN: Adhesion in this system is one of the most important factors that affect the reliability anddurability of repair. According to the many standards and guidelines, e.g. new European StandardEN 1504-10 and ACI Concrete Repair Manual, a pull-off test is recommended for assessment of abond quality in repair systems. The use of pull-off test, due to its semi-destructive character, isrestricted by owners and managers. Therefore, the elaboration of reliable nondestructive method foran adhesion mapping could provide a quite advantageous alternative. Repair system is difficult totest with NDT methods, because of the many factors influencing the stress wave propagation. Inthis paper the possibility of application of various NDT methods for quality control of repairefficiency, including estimation of the bond strength, is discussed.score: 7collation: 28-3
