    Are manufactured from such ingredients as rosin, beef tallow,stereates, foaming agents (soap). They introduce minute air bubbles throughout theconcrete which greatly increases the resistance of concrete to freezing and thawing,increases plasticity and reduces bleeding. Addition of air-entraining admixtures is usuallyin the protection of 3 to 6% of the volume of concrete. These require careful control andmore frequent slump tests. They may also cause some loss of strength.
