Method for measuring chloride ion concentration in concrete structure

摘要

Problem to be solved: to provide a method of measuring chloride ions in a concrete structure using X-ray fluorescence analysis, which is excellent in the quick operation of the whole analysis work and has high accuracy and versatility.A method of measuring chloride ion concentration of concrete structure is a particle size of concrete specimen collected from concrete structure μ A grinding process for grinding fine powder samples up to m and a measurement step for measuring the concentration of chloride ions contained in fine powder samples by the X-ray fluorescence analysis method is performed, and the concrete sample is crushed by the crushing process of the solid 8.Diagram
