Abstract EN
Corrosion depth of concrete can reflect the damage state of the load-carrying capacity and durability of the concrete structures servicing in severe environment.
Ultrasonic technology was studied to evaluate the corrosion depth quantitatively.
Three acidic environments with the pH level of 3.5, 2.5, and 1.5 were simulated by the mixture of sulfate and nitric acid solutions in the laboratory.
354 prism specimens with the dimension of 150 mm × 150 mm × 300 mm were prepared.
The prepared specimens were first immersed in the acidic mixture for certain periods, followed by physical, mechanical, computerized tomography (CT) and ultrasonic test.
Damage depths of the concrete specimen under different corrosion states were obtained from both CT and ultrasonic test.
Based on the ultrasonic test, a bilinear regression model is proposed to estimate the corrosion depth.
It is shown that the results achieved by ultrasonic and CT test are in good agreement with each other.
Relation between the corrosion depth of concrete specimen and the mechanical indices such as mass loss, compressive strength, and elastic modulus is discussed in detail.
It can be drawn that the ultrasonic test is a reliable nondestructive way to measure the damage depth of concrete exposed to acidic environment.
