Testing hardened concrete - Part 12: Determination of the carbonation resistance of concrete - Accelerated carbonation method
Abstract
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.
