1. Consolidate concrete along face of forms and adj acent to transverse joints with an internal vibrator. Keep vibrator away from join t assemblies, reinforcement, or side forms. Use only square-faced shovels for hand spreading and consolidation. Consolidate with care to prevent di slocating reinforcement and dowels.
