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 1-34 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.
