Characteristics of the distribution of vibrators in pack vibration

Conclusions

• 1. For the disposition of vibrators in packs and the design of the schemes for disposition of the packs in the concreted blocks, account must be taken of the simultaneous action of the vibrators on the concrete mix, which makes it possible to increase by 20–25% the output of the compaction process because of a reduction in the vibration time or a decrease in the number of operating positions of the pack.

• 2. For design of the possible schemes for disposition of the vibrator packs it is recommended that use be made of the relations presented in Table 2.

• 3. For operation of packs designed on the basis of the arrangement of single vibrators, the time of vibration of the mix with a given position can be reduced by a factor of approximately 1.5 with respect to the operating regimen of a single vibrator.
