Structural Experts Construction Solutions on Instagram: "Concrete core test for assessing carbonation levels is a standard,semi-destructive, or non-destructive, method used to determine how far CO₂ has penetrated into the concrete. It is critical for evaluating the risk of steel reinforcement corrosion. The primary method is the Phenolphthalein Test, which measures the depth of carbonation by detecting a reduction in the alkalinity (pH) of the concrete pore solution. Uncarbonated (Good) Concrete
