  • TIP 3 - Aggregate Sampling for Laboratory Tests

    At a ready mixed concrete plant aggregates are typically stored in a bin or a stockpile. The process of taking a sample of aggregate that is truly representative of the nature and condition of the aggregate in the stockpile, bin or transfer point is called aggregate sampling. ASTM D75 is the standard practice for sampling aggregates.
