Quality Cement and Concrete - The Role of Testing Laboratories

Abstract
Field inspection (including sampling) and laboratory testing of concrete and concrete-making materials are key activities ensuring that constructed facilities are durable and long lasting. Standards which promote the quality of testing are prepared by ASTM Committees C01 on Cement and C09 on Concrete and Concrete Aggregates, AASHTO, and ISO. The scopes of these standards are discussed and information is provided on their application in testing laboratories. Organizations in the United States which evaluate the competency of testing laboratories are described. This includes the Cement and Concrete Reference Laboratory (CCRL) and the AASHTO Materials Reference Laboratory (AMRL) which are Research Associate Programs located at NIST. CCRL is sponsored by ASTM and AMRL by AASHTO. They operate laboratory assessment and proficiency sample programs used by accrediting bodies to recognize laboratories. The scopes of various laboratory accreditation programs are discussed. In summary, this paper gives an overview of activities being carried out to promote the quality of laboratory testing.Citation
