Excerpt from The Manufacture of Hydraulic Cements, Vol. 3 The following Bulletin deals with the manufacture of hydraulic cements, a subject upon which little reliable information has been spread abroad. That which has been published has been in large portion in other languages than English. The marvelous expansion in recent years in hydraulic cement manu facture and the Portland cement industry, in particular, has resulted in a condition which is undesirable in several respects. Accurate information as to the nature of the raw materials best suited has not been available and hence industries have been established at sites which are now known to be unfavorable, and where the local supplies must be rejected and others transported at a great permanent disadvantage if the output reaches a grade where its use is safe and proper. Also, chemists whose train ing has been so directed as to give them facility in the class of problems here met are exceedingly scarce, and thus many plants have gotten into the way of running along with only the baldest daily essentials from the laboratory instead of asking and receiving from the chemist that class of information and advice which would enable them to rapidly conquer the obstacles and smooth away the difficulties which every new cement industry must inevitably face. Also, managers and directors of cement industries, not being able to obtain in any place a succinct state ment of what has been done in this field of research, have sometimes adopted mistaken and dangerous policies as to their product, because the defects arising are mostly slow to develop and obscure, and have thus placed upon the market thousands of barrels of poor material whose use tends to discredit cements as a class, and prevent the superlative usefulness of good cements from being earlier and more fully recognized. It has been my intent and desire in authorizing and supervising the preparation of this volume to place within the reach of every intelligent person who desires it, a statement of what materials are needed to make good cements, of what mechanical treatment is necessary, and what effects will result from deviations from the prescribed quality of materials or treatment. It is not possible to convey these ideas without constant use of chemical nomenclature and chemical conceptions.
