Why is it called foam concrete

What is foamed concrete?
Foam concrete is an instrumental material used to produce large volumes of relatively low-strength void-filling material; it can easily be pumped long distances and will fill most cavities. Foam concrete is fluid and flowing; it will “search” without requiring leveling or compaction. Moreover, the foam will flow through trenches and encapsulate pipes, fittings, and obstructions. As just a few examples, foam concretes are specified to reduce loadings, reduce site delivery numbers, and provide temporary, stable material for work. Foam concrete is classified as a highly air-entrained sand cement, or cement-only slurry with greater than 20% air by volume. “a cementitious material that consists of minimum 20 percent foam”. The mixes that Propump provides range from 20% 85% by volume of foam. Most of the material provided by Propump has at least 50% foam by volume entrained.
Why is it called foam concrete?
Air is mechanically entrained using a pre-formed foam mixed with the cementitious base material to produce a lighter-density mixed material. On-site foam concretes are typically produced with at least 50% by volume air entrainment, up to 85% depending on the mixes. Their densities range from 400kg/m3 to 1800kg/m3, with strengths ranging from 0.5n/mm2 to 12n/mm2. The name “foam concrete” can be a little misleading; a more apt description would be “foamed mortar” or “foamed Grout” Other common names are “aerated lightweight concrete” and “cellular lightweight concrete,” to name but a few. Foam concrete is used primarily as a void filler; its high expansion rate and fluid properties often make it a much more economical filling material than stiff low, cement concrete or hardcore and lose materials that require compaction.

Pre-foam and Inline methods of foam concrete
This method of producing foam concrete can be completed on or off-site. Foam concrete is produced by part filling a standard ready-mix concrete truck; the rest of the volume is then made up with foam, using the blades inside the “drum” to mix the material. Pumping would occur as a secondary operation. Base mixes for foam concrete differ from typical “concrete” A foam concrete will use sand, cement, and water. The cementitious content, either classed as CEM1 or Ordinary Portland cement, is used. However, cementitious materials such as Pulverised Fuel Ash and Ground Granulated Blast-furnace Slag can be used in various quantities; their use depends on local availability and the reaction level to the various foaming agents used. A foam concrete base mix will have a much higher cement content (minimum 350kg/m3 – 1200kg/m3) than a standard “concrete” mix for slabs or structural concrete. The reason for this is at least twofold.

Price of foamed concrete
Foamed concrete particle size and purity will affect the product's Price, and the purchase volume can also affect the cost of Foamed concrete. A large amount of large amount will be lower. The Price of foamed concrete is on our company's official website.
