Foam concrete

also known as foamedconcrete, foamcrete, cellular lightweight concrete or reduced density concrete, is defined as a cement based slurry, with a minimum of 20% (per volume) foam entrained into the plastic mortar.As mostly no coarse aggregate is used for production of foam concrete the correct term would be called mortar instead of concrete.
