What is foam concrete?

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 foam volume. Most of the material provided by Propump has at least 50% foam by volume entrained. 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.

 

What are the properties of foam concrete

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. 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. Foam concretes specified to reduce loadings, reduce site delivery numbers, and provide temporary, stable material for work, as just a few examples.

 

Pre-foam and Inline methods

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. 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. A foam concrete mix typically has a higher water content than traditional concrete to be pumpable and mixed with foam. Not only this but historically Water reducing agents or plasticizers do not mix well with foaming agents.

 

Price of foam concrete

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