Air Entraining Agent in Concrete

The ability to inject large numbers of small air bubbles throughout concrete mixers, to decrease bleeding, segregation, workability, and improve overall concrete quality, is known as an "air-entraining agent".

Description An Air Training Agent Agent of air-entrainment The ability to mix concrete with a lot of tiny, evenly distributed air bubbles. It helps to decrease the amount of bleeding and segregation. concrete mixture It will increase workability and dramatically improve frost resistance. concrete admixtures .

What's an air entraining device?
The vast majority Air entraining agents These are anionic surfactants. At the water-air interface the hydrophobic groups is directed toward the air. The hydrophobic layer of hydrated particles is formed when the concrete mixture is mixed. The adsorption layers of these air bubbles are all directional and have the same charge. They repel one another, making them easy to distribute evenly.
The anionic air-entraining substances can also be used to prevent bubbles bursting. They are absorbed onto the bubble film by calcium salt precipitation, which is found in high calcium cement.

Characteristics of an air entraining agent
1. You will be amazed at its remarkable properties of long lasting, uniformly fine air bubbles.
2. Concrete can be made more workable and easier to pump.
3. This inhibits water secretion and segregation.
4. Enhances resistance to freeze-thaw and durability.
5. Reducing slump losses
6. You can use it to make concrete for any type of project, such as hydraulic, highway, port or marine.
7. This mortar is compatible with many other types of mortars.

Use of concrete air entrainers
1. Increase the usability of concrete mixes.
2. Significantly increase the concrete's frost resistance and impermeability.
3.Reduce concrete strength. Concrete's strength is affected by its air content. This means that concrete with a higher compressive strength of 1% will shrink by between 4% and 6%. Also, it will have a decrease in its strength for flexural purposes by about 2% to 3.3%.

Be aware Agent for air entrainment
1. This product is not toxic and innocuous, it can be biodegraded, but it cannot be eaten.
2. You should rinse it off with lots of water if it gets in your eyes.
3. A doctor should be consulted immediately if allergies are caused to an organ of the human body.
