ASTM RR:C09-1053 PDF Download

The ASTM RR:C09-1053 standard, also known as the Standard Test Method for Air-Entraining Admixtures for Concrete, was developed to establish a precision statement for the C233 test method.

This standard outlines the procedure for testing air-entraining admixtures, which are additives used in concrete to enhance its workability, durability, and resistance to freeze-thaw damage.

The purpose of the Interlaboratory Study conducted for this standard was to evaluate the precision and repeatability of the C233 test method across different laboratories. By conducting this study, the ASTM committee could determine the level of agreement between test results from different laboratories, providing a measure of confidence in the accuracy and reliability of the C233 test method.

This precision statement is important for the construction industry as it ensures that the results obtained from testing air-entraining admixtures are consistent and reliable across different laboratories. Standardizing the test method through the ASTM RR:C09-1053 standard helps manufacturers, contractors, and engineers make informed decisions regarding the selection and use of air-entraining admixtures in concrete construction projects.
