M. O. Withey
Appears on pages(s):
Data on the influence of external vibration in placing on the properties of over 200 concrete cylinders with cement contents between 3 and 4 sacks per cu yd and W/C ratios, by weight, be- tween 0.50 and 0.77 are given. The advantages in using vibration in placing dry mixes of low cement content is indicated.
