Excerpt from General Specifications for Concrete and Reinforced Concrete, Including Finishing and Waterproofing
Considerable advance has been made in the past ten years in the design and construction of works involving concrete and reinforced concrete and the framing of specifications for that part of the work. Aside from the personal study and efforts of individual engineers, Special Committees from several national organizations have been appointed for the purpose of investigating current practice and providing definite information concerning the properties of concrete and reinforced concrete and to recommend necessary factors and formulas required in the design of structures in which these materials are used.
The American Railway Engineering Association appointed a Committee on Masonry on July 20, 1899, with instructions, as a part of its duties to prepare specifications for concrete masonry. A preliminary set of specifications for Portland cement concrete was reported to and adopted by the Association on March 19, 1903. At the meeting of the Executive Committee of the American Society for Testing Materials, held on December 5, 1903, a special committee on "Reinforced Concrete" was appointed. A Special Committee on Concrete and Steel-Concrete was appointed by the Board of Direction of the American Society of Civil Engineers on May 31, 1904. At the Annual Meeting, held on January 18, 1905, the title of this Special Committee was, at the request of the Committee, changed to "Special Committee on Concrete and Reinforced Concrete." At the first meeting of the Committee on June 17, 1904, it was decided to co-operate with similar committees which had been appointed by the American Railway Engineering Association and the American Society for Testing Materials through the organization of a Joint Committee on Concrete and Reinforced Concrete. The Joint Committee, at its first meeting on June 17, 1004, invited the Association of American Portland Cement Manufacturers to join in its deliberations through a committee appointed for the purpose. The National Association of Cement Users and other organizations have also been working along the same lines as the Joint Committee.
Two meetings of the Joint Committee were held in 1904, five in 1905, two in 1906, five in 1907, two in 1908, and one each in 1911 and 1912. In 1908 the "Special Committee on Concrete and Reinforced Concrete" of the American Society of Civil Engineers began the preparation of the Progress Report which was submitted to the Society in January, 1909.
