Vibration As An Aid In Placing Better Concrete
Lewis H. Tuthill

Particular emphasis is placed by the author on proper handling and placing of concrete to assure benefit of vibration as an aid in placing the most efficient mix, i.e., one having the practical minimum water and cement content. Vibrators are most effective when used to consolidate a uniform concrete placed in a horizontal layer, but their effectiveness is considerably reduced when they must also transport and remix concrete in the forms.
