Defoamer for concrete supplied by our company is a chemical additive specially used to eliminate bubbles in concrete. Its main function is to quickly adsorb and destroy the bubble film through its surfactant components during the mixing process of cement concrete, so that the bubbles burst quickly, thereby achieving the purpose of eliminating bubbles. It can not only effectively reduce the number of bubbles in concrete, but also improve its distribution state, making the concrete more uniform and dense. Concrete defoaming agent is mainly used for defoaming in the production process of cement mortar, water reducer, concrete, asbestos tile, calcium silicate board, putty powder, slurry, enhancer, etc.

Why Do You Need to Use Concrete Defoaming Agent
Improve the quality of the project. After using the defoamer, the surface of the concrete is smoother and flatter, without bubbles or holes, which improves the appearance quality of the concrete. Due to the reduction of bubbles, the density and strength of the concrete are also enhanced, thereby improving the overall quality of the project.
Improve construction efficiency. The addition of defoamer powder or defoamer liquid makes the mixing and pouring process of concrete smoother, reduces construction interruptions and rework caused by excessive bubbles, and improves construction efficiency.
Strong adaptability. Cement concrete defoamer is suitable for various types and grades of cement concrete, and can play a good defoaming effect whether it is on-site mixing or prefabricated component production.
Environmentally friendly and harmless. Modern cement concrete defoamers are mostly made of environmentally friendly materials, which are non-toxic and harmless, and will not harm the environment and human health. Its biodegradability is also good, which is in line with the development trend of the green and environmentally friendly construction industry.
High efficiency, low addition amount, and faster reaction speed than traditional defoamer powder. Usually defoaming is completed within 30 seconds after mixing with water.
Remove mortar black spots and dark spots. Especially suitable for cement-based materials such as grouting materials, self-leveling cement and gypsum products and other materials with special requirements for surface appearance.
Small dosage, high efficiency and low cost of use.
It can effectively control the generation of foam in the cement mortar system, making concrete components more dense and bright.
This product is non-toxic and odorless, which is conducive to production safety and will not cause any pollution to the environment.
Air trapped in concrete can cause concrete to foam and feel light, weak, and brittle. Using a quality defoamer in your concrete countertop mix will help increase the density and strength of your concrete.
Defoamers don’t make air trapped in concrete magically disappear. They work by breaking up the foam that concrete creates during the mixing process. Common ingredients that can create foam are polymers, high-range water reducers, and pigments.
Defoamers help prevent foam from forming in the first place, so air stirred into the concrete during the mixing process doesn’t form foam.
Tiny air bubbles can get stuck inside sand, fibers, and thick, hard concrete. Defoamers break these tiny bubbles apart, creating larger bubbles. Larger bubbles have a better chance of escaping because they can force their way up and out of the mix, but the mix must allow these bubbles to rise and escape on their own.
Because of how they work, defoamers are most effective at removing trapped air when the concrete is very fluid. For this reason, defoamers are best used in conjunction with a strong water reducer like PCE.
Generally, defoamers are added to the concrete mixing plant in a certain proportion and mixed with cement, aggregates, etc. The specific amount of addition needs to be adjusted according to the specific formula of concrete and engineering requirements.
During use, attention should be paid to stirring evenly to avoid local concentration of defoamers in concrete, which will affect its effect. In addition, excessive use may cause the performance of concrete to deteriorate, while insufficient use may not achieve the expected defoaming effect.
