Includes bibliographical references. “This paper outlines the accelerated curing methods used by the Quebec Hydro-Electric Commission, for estimating the 91-day strength of concrete. This is followed by a detailed statistical analysis of the field test data obtained on Outardes -3 project of the Commission using the modified boiling method. Briefly, this method consists of initial standard moist-curing of test specimens for 24 hours, followed by boiling for 3 1/2 hours and measuring compressive strength 1 hour later. The analysis of the field data, which consist of several hundred test results, indicates that the modified boiling method is an acceptable means for potential strength determination of concrete, and its use during the construction of large concrete dams is recommended"--Summary, p. 438.
