Foam Concrete (FC) is made by mixing foam into mortar. The mortar is a cement mix with sand and water. As a result you end up with a mix that is lighter than “normal” concrete. The mass, or density as we call it here, (weight per cubic meter) depends on …Estimated Reading Time: 9 mins
So, small quantities of foam concrete can be produced for small works, like for grouting or trench fill works. This method would provide foam concrete with densities ranging from 300 to 1200 kg/m 3. The foam input will be from 20 to 60 percentage air. The final volume of the foam can be calculated by reducing the amount of other base material.Estimated Reading Time: 9 mins

They are mainly polyurethane (PU) resin-based foams, which cure in contact with moisture when applied. They can be used as a gap-filling, adhesive sealant to fix, fill and insulate against noise, cold, and drafts because they have good insulation properties and are effective at dampening sound.
How to cure foamed concrete. Foamed concrete is a product of mixed foaming and sanding. It has good thermal insulation and sound insulation properties. At the same time, the foamed concrete has lighter weight under the same volume, which can significantly reduce the load of buildings. It has a strong presence in the construction industry.
Boom pumps are truck-mounted concrete pumps with multi-section folding booms that can reach more than 100-meters. They pump concrete at a controlled rate, precisely where it is needed in areas inaccessible to concrete trucks and thereby drastically reduce the cost of labor and speed up construction.
