Description of BS EN 12390-12:2020 2020

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.
