Rebar corrosion is a problem faced by many reinforced concrete structures. The rebar is protected by the alkali component of the concrete surrounding it. Over time, if the surface is oxidized or carbon or chloride penetrates, the alkali component in the concrete disappears and oxygen or moisture penetrates and the rebar begins to corrode. Corrosion of reinforcing bars weakens and cracks the concrete or causes a decrease in the cross-sectional area of rebars, so it is very important to find them at an early stage of corrosion. The Potentiometric Concrete Rebar Corrosion Tester Half-Cell 3023 displays the potential difference between rebar and concrete as a digital value to find the extent of corrosion and the degree of corrosion. This ensures that the entire structure remains safe and can be managed most efficiently. The half-cell inspection method can be used regardless of the diameter of reinforcing bars or the thickness of the concrete cover, and can be used at any time within the life of the concrete. Half-Cell 3023 is supplied with Half-Cell sensor, carrying case, 30m extension cable and aluminum case. MKC supplies the HC-2020 program CD with the equipment for contour mapping of measurement results or for creating reports.
