Committee C-1 on Cement—Seventy-Five Years of Achievement
SourceCommittee C-1 on Cement for the American Society for Testing and Materials convened its first meeting in Philadelphia on Oct. 31, 1902. Seventy-five years have passed; there have been many changes to the original specification for cement adopted in 1904, and additional standards have been written. Many individuals have been involved; there have been special committees, subcommittees, and task forces. The number and complexity of requirements have increased.
Progress during the 75 years is traced in respect to specific requirements and in terms of general topics—strength, soundness, setting behavior, air-entrainment, alkali reactivity, optimum sulfur trioxide and sulfate resistance. Comments are made on the factors and forces which have contributed to the success, pertinence, and growth of specifications under the jurisdiction of Committee C-1 on Cement.
