Application of CCRL Data in the Development of Cement Standards


The Cement and Concrete Reference Laboratory (CCRL) through its Laboratory inspection and proficiency sample programs collects data which are useful in the development of cement and concrete standards. This paper outlines the scope of CCRL activities, discusses specific examples of technical studies which support standard development, and outlines areas of potential CCRL support to standards committees. CCRL inspections are conducted in laboratories equipped to perform tests on cement, concrete, concrete aggregate, and steel reinforcing bars. The program for the distribution of proficiency samples includes portland cement, portland cement concrete, blended cement, and masonry cement. Data from these programs have over the years been made available to the appropriate ASTM committees. CCRL also studies technical problems of interest to ASTM Committee C-1 on Cement and Committee C-9 on Concrete and Concrete Aggregates. Several activities are presented to illustrate the application of CCRL data.
