This document quantifies the carbonation resistance of concrete using test conditions that accelerate the
rate of carbonation. After 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 levels of 70 days.
This procedure is not a method for the determination of carbonation depths in existing concrete
structures.
