ASTM C682-94 PDF Download

ASTM C682-94 is a standard practice that outlines the method for evaluating the frost resistance of coarse aggregates in air-entrained concrete. This practice is specifically designed to be used with normal weight aggregates that do not have a vesicular or highly porous structure. By following this practice, the frost resistance of the aggregates can be assessed, which is crucial in determining their suitability for use in concrete applications. The standard provides guidelines and procedures for conducting critical dilation tests on the aggregates, which involves subjecting them to freezing and thawing cycles. The results obtained from these tests can help in selecting aggregates that can withstand the potential damage caused by frost action and ensure the durability of the concrete.
