Abstract:
In 1917, the Hydro-Electric Power Commission of Ontario, being confronted with a large construction program, became interested in better methods for the production of conrete. About this time too, they decided to abandon the practice of stating the quality of concrete in terms of its proportions and to substitute therefor a classification based on compressive strength at 28 days.
