Vibration and Pervibration in Concrete Depositing

It may be stated in a general way that, for a given nature of sand and a given quality of cement agglutinant the strength of the resulting concrete increases when its compactness increases. The lack of compactness may be due in part to bad granulometry, which is a question into which it is not proposed to enter specifically in this paper; assuming that the best granulometric composition of the inert, component has been attained, lack of compactness may still be due to the fact that full advantage is not taken of the possibilities presented by the composition of the mixture, that air cavities remain in the concrete, either through the presence of mechanically enclosed air bubbles, or through the gradual evaporation of superfluous water.
