EARLY ASSESSMENT OF CONCRETE QUALITY BY ACCELERATING COMPRESSIVE STRENGTH DEVELOPMENT WITH HEAT (RESULTS OF ASTM'S COOPERATIVE TEST PROGRAM)

A cooperative test program was conducted among nine laboratories to evaluate several existing test procedures involving the use of either hot water, boiling water, or the heat of hydration of portland cement to provide heat necessary to accelerate the compressive strength development of concrete. Depending upon which procedure was employed, the amount of acceleration ranged from 1.1 to 2.5 times the strength developed after the same period of moist curing. Statistical analyses of the data justified adoption of a standard method that can be used to judge the quality of concrete soon after mixing. This method designated ASTM C 684-74 involves three procedures of accelerated curing which are limited to concrete made with the same materials and tested by the same laboratory.
