Measurement and long-term observation of cracks in concrete
Result description
The initiation and development of cracks can provide an indication of important problems in concrete pavements, floors, bridges and other engineering structures. Crack initiation reduces not only the durability of structures but also their serviceability. There are several limit values of crack widths in standards and codes, and in the conditions set by developers. Widely-used methods provide only subjective crack width values. Until now, cracks in concrete structures have not been adequately documented. A comprehensive concept for a methodology for measuring cracks on concrete structures is presented in paper. This proposal describes a method for documenting crack layout, measuring crack width and for long-term monitoring of cracks. The accuracy of crack width measurement is analysed on the basis of width tests in laboratory conditions.
