IS 516 : Part 2 : Sec 4 : 2021 Hardened Concrete-Methods of Test - Part 2 Properties of Hardened Concrete other than Strength - Section 4 Determination of the Carbonation Resistance by Accelerated Carbonation Method
New Standard from Last Update.
1 SCOPE
This standard (Part 2/Sec 4) lays down a procedure for evaluating the carbonation resistance of concrete using an accelerated carbonation test. After a period of preconditioning, the test is carried out under controlled exposure conditions using an increased level of carbon dioxide to which, the vertical sides of the specimen are exposed.
The test results are designed to compare the carbonation resistance of similar concretes, which may be used in the same environmental conditions.
