Air-entraining agent
Air-entraining agent, also known as air-entraining agent, is a hydrophobic surfactant. After being dissolved in water and added to the concrete mixture. A large number of tiny air bubbles can be generated during the mixing process.
The air-entraining agent can improve the fluidity, cohesion and water retention of the concrete mixture. And improve the fluidity of the concrete. During the mixing process of the concrete mixture, a large number of uniformly distributed, closed and stable micro-bubble admixtures are introduced.
Air-entraining agents are mainly used in structures that require high frost resistance. Such as concrete dams, roads, bridge decks, airport pavement and other large areas that are prone to freezing.
Use characteristics:
- It can improve the slump, fluidity and plasticity of concrete.
- Reduce concrete bleeding and segregation, and improve the homogeneity of concrete.
- The thermal diffusion and conductivity coefficient of concrete are reduced, which improves the volume stability of concrete. Enhances the weather resistance of field structures and prolongs the service life of road concrete.
- Greatly improved concrete frost resistance, salt resistance, impermeability, sulfate corrosion resistance and alkali-aggregate reaction performance.
Product representative
The main types of air-entraining agents include rosin resins, alkyl and alkyl aromatic hydrocarbon sulfonic acids, fatty alcohol sulfonates, saponins, protein salts, petroleum sulfonic acid, etc.
This product can effectively reduce the surface tension of water, and at the same time, it is based on the principle of synergistic effect of surfactants. We choose the best surfactant to “compound” with it, which improves its performance and reduces the cost of use.
This product is non-toxic, non-flammable, and has no corrosion effect on steel bars. It can be widely used in various pumping constructions such as buildings, roads, bridges, hydraulic and underground projects.
Product performance
- Introduce fine, uniform and long-lasting air bubbles into the concrete mixture, with good foam stability.
- This product can adjust the workability of concrete and improve the poor fluidity and hardening of concrete caused by poor aggregate grading.
- This product can reduce the slump loss of concrete over time.
- This product has a certain auxiliary water-reducing effect and anti-mud effect.
- This product can improve the anti-freezing and thawing cycle ability of concrete, and the effect is better when used with antifreeze in winter.
- This product is suitable for various types of mother liquor.
- The comprehensive use cost is lower.
Instructions
In the process of configuring the pumping agent, according to the workability requirements of concrete, when the dosage is 1.5-3.0%, (0.3-1.5) Kg is added to each ton of liquid pumping agent, and 0.6Kg is recommended, which can effectively improve the concrete. Workability and increase the air content of concrete.
Scope of application
It is suitable for the compounding of polycarboxylic acid, naphthalene series, aliphatic, amino, and other water reducing agents.
