Cement and Concrete #252654

That the use of cement has outstripped the literature on the subject is evidenced by the number and character of the inquiries addressed to technical journals concerning it. This volume is not designed to fill the proverbial long felt want, for until within a few' years the number of engineers using cement in large quantities was quite limited. These American pioneers in cement engineering, under one of whom the author received his first practical training in this line, needed no formal introduction to the use and properties of cement; their knowl edge was born and nurtured through intimate association and careful observation.
