cellular lightweight concrete foaming agent is a special foam producing agent that is useful for the production of cellular lightweight concrete. The foam has a high degree of stability, is resistant to the physical and chemical processes involved in mixing, placing and hardening the concrete.
Stability of foam (when unset) is the most important factor to consider when using a foaming agent to produce cellular lightweight concrete. Foams that collapse before the cement is set can result in a poor final structure.
Several types of foaming agents are available on the market, each with its own benefits. Protein based foaming agents are normally used, but some of the newer synthetic products may also be suitable for use in a cellular lightweight concrete application.
Synthetic foaming agents are also available in a variety of chemistries to suit specific applications. One such product is AERLITE(tm) foam liquid concentrate which is a hybrid formula that combines the performance of protein-based agents with the agility of straight synthetic products.
Aerlite HCR(tm) is a high carbon resistance (HCR) foaming agent that is specifically designed for mix designs incorporating high carbon quality fly ash. It is designed to maintain a stable foam even when it is mixed with Class F and Class C fly ashes.
The aerated foaming agent was added to the mixture of cement, water and sand to make a slurry. The slurry was then whisked to achieve a stable, light weight mass with the desired density.
