This document describes a method for evaluating the carbonation resistance of concrete using
test conditions that accelerate the rate of carbonation. After a defined period of curing and a
period of preconditioning, the test is carried out under controlled exposure conditions using an
increased level of carbon dioxide.
NOTE The test performed under reference conditions takes a minimum of 112 days comprising
a minimum age of the specimen prior to curing under water of 28 days, a minimum
preconditioning period of 14 days and an exposure period to increased carbon dioxide level of
70 days.
This procedure is not a method for the determination of carbonation depths in existing concrete
structures.
