Defoamer for Concrete Admixtures
Today, the concrete industry is advancing. High-performance concrete is now in high demand. To configure high-performance concrete, the selection of concrete defoamer has high requirements.
Concrete defoamers and high-performance water-reducing agents have become essential materials in concrete production. A side effect of using a PCE water-reducing agent is that it will draw excess air into the concrete slurry.
At this time, adding concrete antifoam agents is key to making high-performance concrete. Yuanwang concrete defoamer is your choice.
China Defoamer for Concrete Admixtures
At present, the concrete defoamer has gone through 4 times of renewal. Yuanwang concrete defoamer is the latest generation of defoamer.
It has highly concentrated formula, just one quart covers over 200 cu. ft. of concrete. It overcomes the weaknesses of ordinary ones, like low-temperature resistance and poor permeability.
Yuanwang has an automatic defoamer production line with an annual capacity of 20,000 tons. Defoamer products are widely used in cement mortar, concrete, putty powder, and mineral slurries.

4 Key Functions of Defoamer for Concrete Admixtures
Eliminate foam
The water-reducing agent is a must in concrete. But, its mother liquor has a high gas content. This will create many bubbles during mixing and construction.
The addition of concrete defoamer can make concrete fast defoaming. It reduces surface tension.
Improve the densification of concrete
Yuanwang defoamer works as a densifying admixture in the concrete. After the foam disappears, the pore structure of the concrete can be optimized. This will reduce its porosity and prolong its service life.
Excellent workability
By using an antifoam agent, the surface tension of the concrete is reduced, making it easier to flow, mix, convey, and pour.
It also reduces shrinkage and cracking of concrete and improves its resistance to cracking.
Yuanwang defoamer is suitable for precast concrete, high and ultra-high strength concrete, self-compacting concrete, high-performance concrete, thin-layer or precision structures, and concrete requiring secondary finishing.
Time and cost savings
The use of concrete defoamer reduces the repair work of defects caused by air bubbles.
Reduce cement to lower costs and improve concrete efficiency.

Frequently Asked Questions
Reduced Strength: Too much defoamer will harm the concrete’s water-cement ratio. It will reduce the load-bearing capacity of structures.
Surface Problems: Too much defoamer can cause improper air entrainment. This may harm the concrete’s finish and reduce its durability.
Higher Costs: Overuse of defoamer wastes material and raises costs. It can lead to rework or repairs from poor-quality concrete.
Extended Setting Time: Overdosing on a defoamer can delay the concrete’s setting time. This may disrupt the project timeline and cause delays.
Admixture Imbalance: Too much defoamer can upset the balance of other additives in the concrete mix. This can lead to unpredictable results and harm the mix’s performance.
1. Choose a certified manufacturer. Use a quality concrete defoamer.
2. Add according to the recommended dosage in the instruction manual. Do not exceed it.
3. Follow the correct defoamer dosage, adding time, and mixing method.
4. Strengthen the care and maintenance of concrete, and repair leaks and cracks in time to prolong its service life.
5. Seek the guidance of professionals to provide you with suitable solutions
Enhances the Strength of Concrete Structures:
When concrete experiences foaming, it must be addressed promptly. If not, tiny air pockets will form in the cured concrete. This significantly reduces the density of the concrete, weakening the structural strength. By using a defoamer to eliminate the foam, the concrete can become denser, thereby improving its structural strength.
Improves Corrosion Resistance of Concrete:
For similar reasons, the presence of foam can create air pockets. During the curing of concrete, shrinkage may occur. This will lead to a reduction in thickness and a decrease in corrosion resistance. Foam can cause the concrete to shrink when it cures. This creates an uneven surface with many air pockets. This severely affects the aesthetic appeal and complicates the application of subsequent coatings.
A reasonable combination of concrete water-reducing agent and defoamer is the key to ensuring the quality of concrete.
Concrete water-reducing agent is used to reduce water content and improve permeability. Concrete defoamer can reduce or eliminate foam in concrete. It can also improve its compactness and strength.
However, adding too much or too little of both may have a certain negative impact on the performance of concrete. The amount of addition needs to be controlled based on the situation. This avoids concrete quality issues.
