The aggregates are usually washed and graded at the pit or plant. Some variation in the type, quality, cleanli-ness, grading, moisture content, and other properties is expected. Close to half of the coarse aggregates used in portland cement concrete in North America are
color darker than the standard color, or Organic Plate No. 3 (Gardner Color Standard No. 11), the fine aggregate under test shall be considered to possibly contain injurious organic impurities. It is advisable to perform further tests before approving the fine aggregate for use in concrete. 11. Precision and Bias
Apr 10, 2018 Aggregates are cost effective and stable fillers for concrete. Aggregates contribute to strength of hardened concrete and are stronger than the cement itself. Aggregates are volumetrically stable. Aggregates are typically locally sourced and as such are inexpensive. Cost is the driving factor in aggregate selection.
