Foam concrete, also known as lightweight cellular concrete (lcc), low-density cellular concrete (ldcc), discrete, foamed concrete, foam create, 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.
Foamed concrete is a highly air entrained sand cement or cement only slurry with greater than 20% air by volume. the air is created by the introduction of a preformed foam manufactured using propump engineering’s custom foaming agent (propump 26), encapsulating bubbles of 0.3-1.5mm.
