The term 'Foaming agent' can be refer as a chemical compound, which normally facilitates formation of foam and also helps foam in maintaining its integrity through strengthening every individual bubbles of foam. Uses of foaming agents are become very common in various different industrial processes.
What is foaming agent?
Let's understand the complex term ‘Foaming agent’ into simple words; it can be define as:- a wide spectrum of chemicals act as foaming agent. In almost all cases, the agent acts as a surfactant and also for reducing the surface tension.
Chemists are developing various foaming agents which are more effective for different types of materials.
Area of Usage:
The Protein based foaming agents are commonly known as light weight concrete or also as the foamed concrete. This special type of foaming agent contains some surfactants that are totally natural and when it gets mixed with organic raw materials than it works in synergy. The protein based agents gives very high stability to foam successfully through standing in conditions like casting, hydration process, pouring, conveying (pump-able) mixing. For air entrapped the foam act as binding and it causes no chemical reaction at all.
Using foaming agent is not a hefty task all you need is a bit knowledge and precautions before using it. Just follow the three simple steps as mentioned below:
(i) To form fine foam, first dilute the protein based foaming agent in water (make sure don’t use any other liquid like acid or anything else to dilute it, just use plane water only).
(ii) Now next step is to mix the agent in concrete generator with compressed air the produced foam will be of high stable quality. The density and stability of produced foam depends totally on foam generators dilution and its settings.
(iii) Last step is to add the generated foam in cement and fly ask and make bricks through it.
Application: Normally the foaming Agents are used in the ratio of (250-1400 kg/m3). The true concentration of usage totally depends on the strength of casting, usage of various equipments and on the quantity and quality of water. The protein based foams are used in the production process of various things such as panels, concrete blocks, slabs, void filling and thermal insulation etc.
Shelf life: Usually the minimum shelf lives of protein based foaming agents are approximately of 2 years or even more; the life is totally depends on temperature and locality of storing place. The shelf life becomes more if it is stored in the original containers of foaming agents.
Storage: Temperature either high or low direct affects the productivity of any chemical also the chemicals lost their effectively if they are placed in the contact of direct sunlight. As the direct contact of sunlight affects the chemical same as the freezing temperature also affects the durability and functionality of foaming agent, so it is very necessary to maintain the required temperature of foaming agent to get the desired results from it. Temperature should be below 4900 C for storing foaming agents.

Ecology: The Foaming Agents were very well known as the product which is completely environment friendly, as the product is less toxic for aquatic organisms and it has bio-degradable nature it becomes very Eco-friendly.
Future: Foaming agents have increasing demand in almost all the fields but it gain grips in construction the most in recent time. As the chemical becomes a necessity for modern construction due to various reasons. Addage foaming agents which are totally foam based are used widely in the field of construction.
