What Is The Foaming Agent Used In Foamed Concrete

The foaming agent used in foamed concrete is not a widely recognized or well-known term. However, it can be explained through the process of creating foam that increases the density of concrete and makes it more durable.

To create foam from concrete, first, the mixture is heated until the temperature reaches 190 degrees Celsius, where the surface temperature of the concrete turns to a very hot point. Then, this heat is transferred to the mix by the steam generator or steam fan. As the liquid water molecules start to boil, they vibrate vigorously, causing the liquid to expand rapidly and create a bubble structure called an emulsion. The velocity of these bubbles causes them to spread further into the concrete, creating a frothy, malleable layer of foam.
Thefoaming agent used in foamed concrete is often sodium alginate (NaAlO2), which can react with water to form sodium alginate soap and sodium alginate starch. The soap is then added to the concrete during the mixing stage to make it more dense and harder to crack. The starch is also added as a form of cement to help the concrete withstand high temperatures.
In addition to sodium alginate, other foaming agents can also be used in foamed concrete, such as butyl methylene alcohol (BMA) or propylene carbonate (PC). These agents can affect the density of the foam by reducing its volume, increasing its permeability, and altering its physical properties.
There are several factors that influence the effectiveness of foam made from foamed concrete, including the type of concrete being used, the strength of the application, and the desired texture. For example, if the concrete has a rough surface and requires strong anti-bullying protection, foam made from sodium alginate may be better suited than foam made from brite.

Overall, the foaming agent used in foamed concrete plays a critical role in shaping the shape and durability of the concrete. It can improve the performance of concrete under high temperatures and pressure, increase its resistance to wear and tear, and provide additional benefits for end-users such as increased surface coverage, improved maintenance, and increased durability.
