EUROLAB, with its state-of-the-art accredited laboratories and expert team, offers precise and rapid testing services within the scope of ASTM C227 testing. This test method involves determining the susceptibility of cement-aggregate combinations to expansive reactions involving hydroxyl ions associated with alkalis (sodium and potassium) by measuring the increase (or decrease) in the length of mortar rods containing the combination during storage under specified conditions.
Alkali that participate in expansion reactions are usually obtained from cement; In some cases, they can be obtained from other components of the concrete or from external sources. Two types of alkaline reactivity of aggregates are known:
Data correlating the results of tests carried out using this test method with the performance of cement-aggregate combinations in concrete in use, the results of petrographic examination of aggregates and the results of tests on the potential reactivity of aggregates by chemical methods are used as the basis for Test Method C289 and conclusions and recommendations on the use of cement-aggregate combinations in concrete should be consulted in connection with using the results of tests performed using this testing method.
This standard does not purport to address all safety issues, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and to determine the applicability of regulatory limitations prior to use.
