Foamed concrete is a highly workable, low density material incorporating up to 80% air. To mix a stable foam concrete, it depends on many factors such as, method of foam preparation, selection of foaming agent, addition for uniform air-voids distribution, material grade and mixture design ratio [4]. The produced foam have bubble size which is smaller than the wet foam. The air content is typically between 40 to 80 percent of the total volume. Foam concrete can incorporate a wide range of cement and other combination, for example, 30 percent of cement, 60 percent of fly ash and limestone in 10 percent. If the amount of sand used is higher or coarse aggregates is used other than the standard specifications, there are chances for segregation. The foam concrete properties depend upon the following factors: The influence of water cement ratio has a very little influence on the properties of the foam concrete, unlike foam and the cement content. When the foaming agent is diluted with water and air, further it is mixed into the cement slurry. Compressive strength and density of LWC are the main points of interest in this chapter. Foamed concrete can be produced with dry densities of 400 to 1600 kg/m (25 lb/ft to 100 lb/ft ), with 7-day strengths of approximately 1 to 10 N/mm (145 to 1450 psi) respectively. BS 8443:2005 covers the foaming admixtures. The foam concrete properties in its fresh and hardened state are explained below; The exact comparison for the foam that is manufactured to produce foam concrete resembles the shaving foam. For more densities, say greater than 1500kg/m3 more filler and medium sand is employed. Propump Engineering Ltd A solution of water and the foaming agent is forced by restrictions into a mixing chamber by compressor air. Many Department of Transportation (DOT) projects required the use of polyurethane over any other alternative material. The dry density of foamed concrete may vary from 300 to 1600 kg/m3.
