ASTM RR:C09-1008 PDF Download

The ASTM RR:C09-1008 standard focuses on the sampling and testing procedures for fly ash or natural pozzolans to be used in Portland cement concrete.

The standard provides guidelines for conducting interlaboratory studies (ILS) to evaluate the precision of testing methods. The ILS was conducted between 1987 and 1989 and involved seven different laboratories.

During the study, four samples were tested using ASTM C311, a test method specified in the standard. The purpose of the ILS was to establish a precision statement for ASTM C311 by comparing the results obtained from different laboratories.

The results of the ILS are reported in this research report. The report provides valuable insights into the consistency and reliability of the testing method and helps ensure that fly ash or natural pozzolans used in Portland cement concrete meet the required standards.
