Method and system for estimating filling depth of cracked repair material and method for selecting crack repair material

摘要

PROBLEM TO BE SOLVED: To provide a method and a system for estimating a filled depth of a crack repair material, as well as a method for selecting a crack repair material, capable of accurately estimating the filled depth of a repair material before repair work of cracks of diverse widths that could develop on a concrete structure, thus helping to select an optimum repair material in view of the filled depth.SOLUTION: A method for estimating a filled depth of a crack repair material comprises: a first step in which a crack of a prescribed width developed on a concrete structure is simulated by immersing a glass tube 1 having an inner diameter that equals the prescribed width into a tray 2 filled with a crack repair material m, and an infiltration height of the crack repair material m in the glass tube 1 is measured; and a second step in which a filled depth is estimated when the crack repair material m is filled into the crack of the prescribed width that developed on the concrete structure, on the basis of the measured infiltration height.
