Keywords: chloride in concrete, near-infrared spectrometry, rapid determination. 1. INTRODUCTION. 1.1 Background. Penetration of chloride ions into concrete is a well-known problem, because it eventually results in. corrosion of rebars, leading to cracks, spalling, delamination and other roadway defects [1].
