Various types of concrete are manufactured based on materials, mix design, means of construction, and area of application. Which type of concrete is made by introducing a foaming agent?

Air-entrained concrete helps relieve internal pressure by providing small pockets for water to expand into when it freezes. Resins, alcohols, and fatty acids are all examples of air-entraining agents for this type of concrete.
