Title: Progress in Investigation of Cement Mortars and Concretes in the Structural Materials Testing Laboratories of the U.S. Geological Survey, St. Louis, MO.
Author(s): Richard L. Humphrey

Abstract:In the interval which has elapsed since the opening of the Model Testing Laboratory of the Association of American Portland Cement Manufacturers at the Louisiana Purchase Exposition, Septemeber 1st, 1904, a great deal of work has been in the enlargement both in the equipment and the scope of what is now the Structural Materials Testing Laboratories of the U.S. Geological survey. The Laboratories are to-day, by all odds, the best equipped in this country and possess facilities for making the various tests required in the investigation of structural materials. By reason of the urgent need for information on the subject of Concrete and Reinforced Concrete the work has been largely confined to tests of this material. There has probably never been attempted such an elaborate series of investigations and the result should be of the highest possible value to every user of cement. The main value lies in the fact that the investigations are of a practical character, covering studies as to the working stresses to be used in the design of various forms of concrete construction.
