Foam concrete, foamed concrete, aerated lightweight concrete, cellular lightweight concrete

Foam concrete, also called foamed concrete, cellular concrete, cellular lightweight concrete, or aerated lightweight concrete, is a construction material that is known worldwide. As almost no aggregate is used for production of foam concrete, the correct term would be mortar instead of concrete. The overall term, "cellular concrete", normally contains so-called foam concrete as well as autoclaved aerated concrete. Autoclaved aerated concrete is a standardized construction material, whereas foamed concrete is normally approved in accordance to the autoclaved aerated concrete norms.

Autoclaved aerated concrete

Autoclaved aerated concrete
, also known under the brand name "Ytong" or "Siporex", can only be produced in special plants. The highly explosive element hydrogen, as a reaction of cement, lime, sand and aluminum, is used as an expanding agent to build pores or air in the concrete. This process is very hard to control, costs a lot of energy and requires a high investment in immobile machinery.

Foam concrete

Foam concrete, the other type of cellular lightweight concrete, is produced with harmless foam, which is mixed into the slurry. A foaming agent is diluted with water and expanded with air within a foam generator and is then added into a cementitious slurry. The product can be air cured or the curing process can also be accelerated by vapor or steam curing up to 70°C. This procedure is by far simpler and easier to control and requires less energy. 

Foaming agent, LithoFoam

Foaming agents are classified based on the active ingredient:

•Protein based
•Surfactant based (synthetic foaming agents)
•Enzyme based (new technology by Luca Industries International) 

Protein based standard foaming agents are made by protein hydrolysis from animal proteins out of horn, blood, bones of cows, pigs and other remainders of animal carcasses. This leads not only to occasional variations in quality, due to the differing raw materials used in different batches, but also to the very intense stench of such foaming agents.

Surfactant based foaming agents are purely chemical products with constant quality, but still possess insufficient properties and low efficiency for the manufacturing of foam concrete.

Enzyme based foaming agents are a new and innovative foaming agent technology by Luca Industries International. LithoFoam consists of highly active proteins of biotechnological origin and is not based on the unattractive protein hydrolysis. LithoFoam tops all other types of foaming agents with its superior quality and properties, a very competitive price and a neutral, technical odor. 

Foam generators

Foam generators of Luca Industries International work with a unique low pressure air system. The foam generators therefore generate, in combination with the unique foaming agents, a very constant foam that is subject to precise adjustments if necessary.
