ASTM RR:C09-1017 PDF Download

ASTM RR:C09-1017 is a research report that focuses on evaluating the within-laboratory precision of the length change method for determining the resistance of concrete to rapid freezing and thawing. The report specifically aims to establish precision statements for the ASTM test method C666, which involves subjecting concrete beams to cycles of freezing and thawing.

The study described in the research report involves multiple laboratories conducting tests using the length change method to measure the impact of rapid freezing and thawing on concrete. The objective is to assess the repeatability and variability of the results obtained by different laboratories, in order to establish the level of precision for the test method.

By determining the within-laboratory precision of the length change method and establishing precision statements for C666, this research report contributes to the standardization of testing procedures for evaluating the resistance of concrete to rapid freezing and thawing. This ensures that consistent and reliable results can be obtained across different laboratories, enhancing the reliability and comparability of test data in assessing the durability of concrete in freezing and thawing conditions.
