I had the same question. They are also called "air entraining agents." They are essentially generic or proprietary industrial detergents marketed under a wide variety of brand names. They are used with a machine called a "foam generator" to introduce tiny bubbles into the concrete mix and maintain the bubbles until it hardens.
I also found that aluminum powder can serve as a foaming agent for concrete, but I don't think that it is commonly used, since that would be a very expensive proposition.
What else can I help you with?
Water-reducing agent in concrete?
A water-reducing agent, also known as a plasticizer, is an additive used in concrete to reduce the amount of water needed for mixing while maintaining workability. This helps improve the strength and durability of the concrete by increasing its density and reducing the water-to-cement ratio. Water-reducing agents can also enhance the flowability of the mixture, making it easier to handle and place. They are particularly beneficial in applications where high strength and performance are required.
What oil used for concrete form?
The oil commonly used for concrete forms is typically a form release agent, often made from mineral oils or vegetable oils. These oils create a barrier between the concrete and the formwork, allowing for easy removal of the forms after the concrete has cured. Some products may also include additives to enhance performance, reduce surface defects, and improve the finish of the concrete. Always check for compatibility with the specific type of form material being used.
What is difference between MS rods and TMT bars?
TMT Bars - High strength deformed steel bars used for concrete reinforcement. The surface has many short ribs to allow the concrete to adhere better than if the bars had a smooth surface.MS Rods - Mild Steel rods are used to construct many things (such as scaffold construction), but are not the best choice for concrete. The surface of the rod is smooth, so it does not allow the concrete to adhere as well as if the surface had a texture.
What is c16-20 cement?
C16/20 cement refers to a classification of concrete strength, specifically the characteristic compressive strength of concrete at 28 days. The "C" denotes concrete, while the numbers indicate the compressive strength in megapascals (MPa) for different types of concrete mixes. In this case, C16/20 indicates that the concrete mix can achieve a minimum strength of 16 MPa in cubes and 20 MPa in cylinders. This classification is commonly used in structural applications where moderate strength is required.
What are the advantages of enriched uranium?
It could be used with light water reactors.
What are the commonly used methods for curing foam concrete?
Concrete recycling
What is an anti-foaming agent?
simethecone and other non-foaming detergents are good anti-foaming agents.
How is the use of foaming agents in food regulated to ensure consumer safety and product quality?
The use of foaming agents in food is regulated by government agencies such as the FDA in the United States. These agencies set limits on the types and amounts of foaming agents that can be used in food products to ensure they are safe for consumption. Additionally, food manufacturers are required to follow Good Manufacturing Practices (GMP) to maintain product quality and safety standards. Regular inspections and testing are conducted to ensure compliance with these regulations.
What is the anti-foaming agent that's used in hot tubs made of?
The fast answer is Silicone Oil - that is the ingredient in anti-foam agents for hot tubs that does the foam killing.
What role does silicone anti-foaming agent play in food production processes?
Silicone anti-foaming agents are used in food production processes to prevent excessive foam formation during cooking or processing. They help maintain the desired texture and appearance of food products by reducing the amount of air trapped in the mixture.
What is foaming cream?
Foaming cream is an ointment used to treat delicate facial skin and to prevent skin irritation.
What is fluorescence in concrete?
Fluorescence in concrete is the property of emitting visible light when exposed to ultraviolet light. This phenomenon can be achieved by adding fluorescent materials, such as pigments or dyes, to the concrete mixture. Fluorescent concrete can be used for decorative purposes in indoor and outdoor applications.
What is used to reduce a bubbling substance?
A defoaming agent is typically used to reduce bubbling in a substance. These agents work by breaking the surface tension of the bubbles, causing them to collapse and disappear. Defoaming agents can be added directly to the substance that is bubbling to help control and prevent excessive foaming.
For lightweight foamed concrete how much foam is used in adequate mix of foam cement and water?
you can see the example : if you porduce 600kg/m3 foamed concrete ,you will need foaming agent about 0.5kg ,cement is 600kg, water is 300kg ,of course ,the density is lower ,the foaming agent need more ,the foam need more . we suggest you visit our website to read more information : httP://www.foamed.com.cn ,or send us email:heyimy@gmail.com
Can hydrofluoric sulfuric acid be used on windows and concrete?
No, hydrofluoric sulfuric acid should not be used on windows and concrete. It is a highly corrosive and dangerous chemical that can cause severe burns and damage to surfaces. It is important to use safe and appropriate cleaning agents for windows and concrete.
What is Roman concrete?
The Romans in 127 AD used crushed pumice for aggregates in cement (light weight concrete) for walls of Pantheon in Rome
What are the names of locating agents in paper choromatografy?
The locating agents commonly used in paper chromatography are ninhydrin, iodine vapor, and UV light. These agents help visualize the separated components on the paper chromatogram.
