CCANZ - Impurities and Other Harmful Materials

Besides reactive minerals, aggregates may contain other impurities, such as organic matter, which are harmful to concrete. Organic matter, such as that derived from decaying vegetation, is capable of delaying setting and hardening of concrete. It is more likely to be found in fine than in coarse aggregate and may be detected by the test set out in NZSMETHOD OF TEST FOR ORGANIC IMPURITIES IN CONCRETE,a. Fine Aggregate Level 130 mL, and b. NaOH Solution Level 200 mL. 2. Sodium hydroxide solution: 3 %. Dissolve 30 g of sodium hydroxide pellets, NaOH analytical reagent, in one liter of water. 3.
