Abstract:
Data are presented covering the period 1974 to 1976 inclusive as collected by Manitoba Hydro and by R.M. Hardy and Associates Ltd. The former is a public utility and the latter a consulting engineering group. The Mani-toba Hydro results are from a project in Northern Manitoba utilizing CSA Type 10 (ASTM Type 1) portland cements manufactured in both Manitoba and Ontario. Results from the Hardy group were collected on a number of projects in Southern Alberta - principally sidewalk concrete control work in the City of Calgary and a gas plant near Pincher Creek, Alberta. Results from CSA Types 10 and 50 (ASTM Type I and V) portland cements are presented separately. Regression equations are developed and compared with equations prepared from earlier Western Canadian data.
