Standard Test Methods for Cements that Require Carbonation Curing

Importancia y uso:

4.1 These test methods are used to develop data for comparison with the requirements of Test Methods C1910/C1910M or other specifications for cements that require carbonation curing. These test methods are based on standardized testing in the laboratory and are not intended to simulate job conditions. All tests are performed with mortar and therefore, the results may not provide a direct correlation of how the tested cementitious material will perform in concrete.

4.2 Compressive Strength—The test for compressive strength is used to determine whether the cement tested will develop a minimum level of strength when carbonated under laboratory conditions.

4.3 Chemically Bound Carbon Dioxide—Determined using mortar cube specimens prepared for determining compressive strength, the test for chemically bound carbon dioxide is used as an estimate of the mass of carbon dioxide bound during the carbonation curing process and is expressed as a percent of the mass of cement in the test mixture. The actual amount of carbon dioxide bound in a manufactured product is affected by the carbonation process and the cement used, and the physical characteristics of the manufactured product.
