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 1-12 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
