What is a cement waterproofing agent?

 

Cement waterproofing agent means that under certain conditions, it can prevent, delay or reduce the damage of cold and heat bridge crystallization and chemical reaction on the surface or inside of concrete, and has good freeze-thaw resistance (such as thickening, emulsion stability, etc.). freezing point lowering admixture. The main components of cement waterproofing agent are: high-efficiency penetrating base layer treatment agent; multi-functional modified polymer rubber powder and its compound system; appropriate amount of active catalytic assistant.

 

Cement waterproofing agent is made of modified synthetic polymer polyurethane and various active chemical raw materials through scientific ratio and complex physical reaction. It is an inorganic, non-toxic and harmless polymer with high molecular weight. High-quality functional rubber powder material that rapidly cures and hardens in the environment, which is characterized by: forming a gel when interacting with water; hardening or softening (in contact with water) on wet substrates; non-corrosive; excellent durability .

What are the characteristics of cement waterproofing agent?

 

1. It can improve the adhesion between the mortar and the wall or between the base layer;

 

2. Enhance crack resistance and elongation to make it more durable;

 

3. Improve the internal microstructure of concrete;

 

4. Inhibit alkali aggregate reaction, good crack resistance, durability and stability;

 

5. Reduce shrinkage, have superior permeability and good adhesion;

 

6. Reduce the cost of concrete construction;

 

7. Speed ​​up the concrete construction speed.

 

What are the uses of cement waterproofing agent?

 

Cement waterproofing agent is a new type of multifunctional polymer material, which has good adhesion. It can be widely used in construction engineering, roads and bridges and other fields, and plays an important role in improving construction quality and safety production.

 

1. Increase the strength of concrete. After adding an appropriate proportion of concrete penetrating and sealing additives when preparing concrete, it not only makes the concrete denser and reduces cracks, but also greatly reduces the air bubble content and capillary porosity in the concrete; at the same time, because of its extremely small proportion The liquid components of the reinforced concrete are adsorbed and blocked inside the microscopic channels of the concrete, thereby preventing the external moist gas or pollutants from eroding the surface of the reinforced concrete, achieving durable anti-corrosion effect and prolonging the service life of the concrete.

 

2. Improve the flow of concrete. Since there are many voids (such as honeycomb hemp surface) between the mortars in the concrete, it is easy to cause instability in the internal structure of the concrete. The use of waterproofing agents can increase the contact area between the aggregates and reduce the void ratio. , thereby increasing its strength and compactness.
