Excerpt from Portland Cement Materials and Industry in the United States This report has been prepared in order to give information desired by two classes of persons - owners of lands on which marl, limestone, or clay deposits are found, and cement manufacturers or those who desire to become such. For the benefit of those of the first class, who wish to know whether a given material is suitable for Portland cement manufacture, the writer has attempted, in Parts I and II of the report (pp. 16 to describe the chemical and physical prop erties which a Portland cement material must have, and above all to show that the value of cement material depends almost entirely upon its location with respect to fuel supply, transportation routes, and markets. For cement manufacturers present and prospective, who want to know at what localities in a given State or group of States cement materials will probably be found and who desire information in advance of actual testing as to the physical and chemical character of the materials, Part III (pp. 67 et dealing with the cement resources of the separate States, has been prepared. The report is intended to be a discussion of the Portland cement materials of the United States, not a manual of cement manufacture nor a guide to cement testing or utilization. A brief Sketch of the general status of the Portland cement industry is, however, presented in Part I, in order to make the subject clear to the great number of people who are interested, in one way or another, in the condition and growth of this important branch of manufacture.
