Foamed concrete - Quality control

Foamed concrete is produced either by adding a quantity of preformed foam to a mortar or paste directly into a truck mixer or via a special in-line mixer using ready mixed mortar or paste. Typically only plastic density is routinely measured together with sealed cube strength (note 150mm cubes should be used due to the low strength of foamed concrete).
