Concrete Corrosion Testing Equipment: Mapping System

Concrete Corrosion Potential Mapping System

Concrete Corrosion Mapping System quickly determines if concrete surfaces have chloride-induced corrosion in reinforcing steel. Half-cell method. Use on bridge decks, pavement, walls, etc. Proper contact between electrodes and concrete surface is crucial for accurate measurements. Device can measure various properties of reinforced concrete including corrosion rate. Prepare concrete surface, make sure it’s wet and know the depth of cover. Technology also predicts properties of concrete materials and steel reinforcement and can measure polarization resistance and electrical resistivity.

Reinforcing steel in concrete is normally passive to corrosion until chlorides from the environment get into the concrete and start an electrical current flow. Half-cell measurements measure corrosion activity with a probe electrically connected to the concrete through a water saturated sponge. A separate cable is attached to rebar in the structure, completing the circuit. Readings correlate to steel corrosion activity near the probe. Readings can be plotted on paper or on the concrete to give a graphic of the structure. A Rebar Locator is recommended to accurately locate bar position.

Introduction

Detection and evaluation of corrosion in reinforced concrete structures is key to their durability and longevity. Corrosion of steel reinforcement can cause structural damage, safety risks and costly repairs. Advanced non-destructive testing methods and equipment like iCOR Corrosion Detection Technology has changed the game in corrosion detection and monitoring. This technology allows users to quickly and accurately assess the condition of reinforced concrete structures, identify high corrosion risk areas and perform repairs. In this article we will go over the principles of corrosion, rebar corrosion identification, non-destructive testing methods and applications and benefits of corrosion detection in reinforced concrete structures.

Principles of Corrosion

Corrosion is the deterioration of materials such as steel reinforcement due to chemical reactions with their environment. In reinforced concrete structures corrosion occurs when the steel reinforcement is exposed to moisture, chlorides and other corrosive substances. The corrosion process can be accelerated by factors such as temperature, humidity and presence of cracks or defects in the concrete. Understanding the principles of corrosion is key to developing effective corrosion detection and prevention strategies. Electrical resistivity of concrete, polarization resistance and corrosion potential measurement are all critical parameters in assessing corrosion risk in reinforced concrete structures.

Rebar Corrosion Identification

Rebar corrosion identification is a critical step in maintaining the integrity of reinforced concrete structures. Non-destructive testing methods such as half-cell potential measurement and electrical resistivity testing can help identify high corrosion risk areas. iCOR Corrosion Detection Technology for example uses high precision sensors to measure the electrical resistivity of concrete and steel reinforcement to give accurate and reliable results. By identifying rebar corrosion users can perform targeted repairs and prevent further deterioration of the structure.

Non Destructive Testing Methods

Non-destructive testing are used to evaluate the condition of reinforced concrete structures without damaging them. NDT such as compressive strength testing, half-cell potential measurement and electrical resistivity testing can provide valuable information about the structure’s properties and condition. NDT techniques can help identify high corrosion risk areas, detect defects or cracks in the concrete and assess the effectiveness of corrosion prevention measures. iCOR Corrosion Detection Technology for example uses a combination of NDT to give a comprehensive assessment of the structure.
