Abstract

Objectives: Determination of the degree of saturation and chloride penetration in cracked hydraulic concrete structures. Methods: Depending on Electrical Conductivity (EC) principle, developed method called Electrical Conductivity Technique (ECT), was submitted for purposes of evaluating and calculating the accurate degree of saturation and amount of chloride penetration in mentioned structures. Many experimental specimens were used for test this method and compered with numerical result. Findings: The experimental results were obtained by using this new test, agreed fairly with results which obtained from numerical solutions. So the developed ECT is the more suitable method for determining the degree of saturation and penetration of chloride ions in the laboratory. Application/Improvement: This research ensures a novel application for the use of the electrical conductivity principles to find the chloride concentrations in the concrete model with a very precise manner, which contributes to better understanding of the penetration processes in terms of salts or saturation within the concrete structures.
