EUROLAB, with its state-of-the-art accredited laboratories and expert team, offers precise and rapid testing services within the scope of ASTM C88 testing. This testing method involves testing aggregates to estimate their durability when exposed to weathering in concrete or other applications.
This is accomplished by repeated immersion in saturated solutions of sodium or magnesium sulfate and subsequent oven drying to partially or completely dehydrate the salt precipitated in the permeable pore spaces. The internal expansion force obtained from the rehydration of salt upon re-immersion simulates the expansion of water during freezing.
This test method provides information to help evaluate the durability of aggregates when sufficient information is not available from service records of the material exposed to actual weather conditions.
Permissible values of percentage loss by this test method are generally different for fine and coarse aggregates and attention should be paid to the fact that test results using the two salts differ significantly and care must be taken in determining appropriate limits in any given case.
Specifications containing the requirements for these tests. The test is usually more severe when magnesium sulfate is used; Accordingly, the allowable percentage loss limits when magnesium sulfate is used are normally higher than the limits when sodium sulfate is used.
This standard does not purport to address safety issues 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.
