Carbonation depth measurement of specimens. (a) The cube cleavage test of specimens in groups SP1 and SP2. (b) One splitting surface of sample blocks with phenolphthalein. (c) The measurement of carbonation depth of beams in groups SP3∼SP5 during the corrosion test. (d) The measurement of the carbonation depth of beams in groups SP3∼SP5 after the carbonation test. (e) The degree of carbonation depth before the carbonation test.
