Abstract:
During the 1925 convention in Chicago, the representative of The Detroit Edison Company was much impressed by a paper on concrete control presented by an engineer of the Pennsylvania Railroad. Two very simple ideas were impressed on his mind; first, excess water as an ingredient of concrete can have no structural value; second, the elimination of excess water increases the structural strength of concrete. From these two ideas it seemed inevitably to follow that quality concrete should pay dividends in the form of cement saving. In other words, the whole program seemed to afford another illustration of what is so frequently encountered, namely, that the producer who for the sake of high quality strictly adheres to the best methods, finds himself financially rewarded thereby. However, as a chain is no stronger than its weakest link, it followed that concrete control must be complete or it would be dangerous.
