Effect of Vibration on Air Content of Mass Concrete.
Abstract
Tests were made to observe the effect of high-frequency (13,000 vpm) and moderate-frequency (6800 vpm) vibration on concrete ranging from dry to wet consistency, containing 6-in. coarse aggregate, and having nominal air contents of 3, 6, and 9 per cent in that portion of the mix smaller than 1-1/2 in. Cores drilled from hardened specimens of the concrete with 6-per-cent air content were examined micrometrically for amount and distribution of air and coarse aggregate. (Author)
