Product Features:
1. Reduce the sensitivity of concrete to water and admixtures
This product effectively reduces the sensitivity of concrete to water and admixtures through specific chemical composition and mechanism of action.
After adding SH-2N to concrete, concrete can better adapt to the changes of different water sources and admixtures, and maintain its stability and working performance.
2. Improve the encapsulation of concrete, prevent sand and gravel from settling, and reduce segregation
SH-2N can significantly improve the encapsulation of concrete, ensuring that the aggregates in the concrete (such as sand and gravel) are fully encapsulated by the cement paste.
This increase in encapsulation helps prevent the occurrence of sand and gravel settling and segregation, making the concrete more uniform and stable.
3. Improve the pumping efficiency of concrete
Since SH-2N can improve the fluidity and pumpability of concrete, it can significantly improve the pumping efficiency when pumping concrete.
This not only reduces energy consumption and wear during pumping, but also speeds up the construction progress and improves construction efficiency.
4. Water retention does not affect fluidity, water reduction rate, or concrete strength
SH-2N has good water retention performance and can form an effective water retention system in concrete to reduce water evaporation and loss.
While retaining moisture, SH-2N does not affect the fluidity and water reduction rate of concrete, ensuring that the concrete has good working performance.
Most importantly, the addition of SH-2N does not have a negative impact on the strength of concrete, ensuring the quality and service life of concrete.
FAQ
1. What is a concrete suspending agent?
Concrete suspending agent is a special chemical agent used for concrete surface treatment, usually in powder or liquid form. It has many functions such as improving the fluidity, dispersibility and crack resistance of concrete, which can effectively improve the quality of concrete, especially under special conditions such as high temperature and high humidity.
2. What is the role of concrete suspending agent?
Improve concrete fluidity: Concrete suspending agent can reduce the friction between particles in concrete, making it easier for concrete to flow in the formwork, thereby better filling the formwork gaps and reducing the appearance of bubbles and capillaries.
Prevent bubbles and cement separation: Adding an appropriate amount of suspending agent to concrete can improve the bonding ability of concrete, reduce the generation of bubbles in concrete, prevent the separation of cement and water, and thus improve the strength and durability of concrete.
3. What are the types of concrete suspending agents?
Concrete suspension stabilizers can be roughly divided into four categories according to their chemical composition and working principle:
Phosphate stabilizers: generally tricalcium phosphate, sodium silicate and hydraulic phosphate paste as the main raw materials, with excellent coagulation and waterproof properties, can inhibit the carbonization reaction inside the concrete, and extend the service life of the concrete.
Organic acid stabilizers: The main components are fatty acids, fatty acid salts and amine compounds, which can interact with the surface of cement colloids through adsorption such as hydrogen bonds, improve the rheological properties of concrete, prevent water penetration, and improve the frost resistance and acid and alkali resistance of concrete.
Protein colloid stabilizers: mainly include gelatin, collagen, hard protein and bovine serum albumin, which can form a bonding matrix, increase the adhesion and hardness of concrete, and improve the compression and shear resistance of concrete.
Polymer stabilizers: divided into inorganic polymers and organic polymers. Inorganic polymers have the characteristics of solubility, low viscosity and good stability; organic polymers have good stability, low viscosity and small addition amount.
4.What are the application scenarios of concrete suspension agents?
Concrete suspending agents are suitable for a variety of application scenarios, including but not limited to:
Pumping concrete: ensure that the concrete maintains high fluidity and stability during the pumping process.
Self-compacting concrete: improve the compactness and uniformity of concrete, reduce voids and bubbles.
Other cement-based products: such as mortar, gypsum-based materials, etc., used to improve their fluidity and working performance.
5.How to choose a suitable concrete suspending agent?
Choosing a suitable concrete suspending agent requires consideration of the specific application environment, working requirements and performance requirements of concrete. It is recommended to select the concrete suspending agent based on the actual situation of the project, combined with the type, characteristics and scope of application, and conduct sufficient testing and verification before use.
