The present is an era of specialization in concrete proportioning, in which the old standards are rapidly being discarded and new paths to new and better standards sought in many directions. Many new paths have been reported in the Proceedings of the American Concrete Institute among which those of Abrams, Young and McMillan are notable. This paper describes the path followed in proportioning and handling the concrete on an important public work in the city of Chicago, in which some partially appreciated truths have appeared to have much greater bearing on this matter than is generally realized.
