Organic Impurities in fine aggregates
Organic impurities, usually in the form of tannic acid and its derivatives, are typically present in fine aggregates such as sand. These may interfere with the chemical reaction of hydration and may effect the strength of the mortar or concrete where the aggregates are used. The test method for this determination conforms to the alternative procedure specified in ASTM C40.
