Title: Air Entrainment in Cement and Silica Pastes

Abstract:The air-entraining capacities of a number of surface-active agents in cement and silica pastes were measured by a standard test procedure. In addition, measurements were made of the foaming properties of surface-active agent solutions with and without electrolyte additions, and of the abilities of surface-active agents to make cement and silica particles hydrophobic by adsorption so that air bubbles adhere to them. These sets of data were used to demon-strate the conditions governing the formation of stable, air-entrained pastes containing surface-active agents, and the mechanisms by which air bubbles are introduced into and retained in pastes.
