Investigation of Cement-Replacement Materials. Report no. 9. Significance of Pulse-Velocity Data for Mass Concrete Blocks,
Abstract
In Phase D (previously reported) of the cement-replacement materials investigation, 25 concrete test blocks, 5 by 100 by 20 ft, were made, each of a different concrete mixtures diffused only in cement factor (ranging from 1-3/4 to 4 bags per cu yd) and type and amount of cement-replacement materials used. The blocks were tested for ultrasonic pulse velocity, at ages ranging from 2 to 360 days, to provide data on performance of cement-replacement materials in mass concrete under field conditions. Variations in the Phase D pulse-velocity data stimulated the investigation reported herein, which has as its objective the development of data on: Pulse velocity of aggregate used in the Phase D blocks; Influence on the pulse velocity of concrete of (1) aggregate pulse transmission path; Relative influence of pulse velocity of fine and of coarse aggregate on pulse velocity of concrete; Means of interpreting observed pulse velocity of concrete in terms of properties of paste phase of the concrete.
