    Abstract

    ASTM Specification for Fly Ash and Raw or Calcined Natural Pozzolan for Use as a Mineral Admixture in Portland Cement Concrete (C 618) is probably the most demanding specification for fly ash in the English-speaking world, with comprehensive provisions for both chemical and physical tests. However, the time delays involved and the cost of testing are often out of proportion to the benefits derived. ASTM Standard Methods of Sampling and Testing Fly Ash or Natural Pozzolans for Use as a Mineral Admixture in Portland Cement Concrete (C 311) does a creditable job of defining test methods to meet the needs of C 618, but neither document makes any attempt to grade testing frequencies for individual tests in a practical manner. With the new ASTM Committee C09.03.10 beginning the task of revising the documents, this seems a good time for a critical look at the status quo.
