Anionic polyacrylamide is a very good raw material for concrete admixtures, especially its hydrophilicity, high viscosity, flocculation and so on. It is very suitable for use in concrete admixtures.
When anionic polyacrylamide is used in concrete admixtures, the products produced have a very good effect on improving the properties of concrete. For example, when anionic polyacrylamide is used as a thickener, it can increase the adhesion of concrete on the wall, and can also make the concrete coagulate better under water; when anionic polyacrylamide is used as a water reducing agent, It can increase the fluidity, strength and tightness of concrete; when Gongyi Haijiang anionic polyacrylamide is used as a retarder, it can prolong the setting time of cement; when anionic polyacrylamide is used as antifreeze, it can reduce the concrete; Freezing damage, reducing the probability of cracking of concrete under low temperature conditions, etc.
Anionic polyacrylamide is a very good concrete admixture
Concrete admixtures made of anionic polyacrylamide have the following effects:
1. It can reduce the water consumption of concrete, or increase the fluidity of concrete without increasing the water consumption.
2. The concrete setting time can be adjusted.
3. Reduce bleeding and segregation, improve workability and water washability.
4. It can reduce the slump loss and increase the pumpability of pumped concrete.
5, can reduce shrinkage, adding expansion agent can also compensate for shrinkage.
6. Delay the initial hydration heat of concrete. Reduce the temperature rise rate of mass concrete and reduce the occurrence of cracks.
7. Improve the early strength of concrete and prevent freezing under negative temperature.
8. Improve strength and increase frost resistance, impermeability, abrasion resistance and corrosion resistance.
9. Control alkali-aggregate reaction, prevent steel corrosion and reduce chloride ion diffusion.
10, made of other special properties of concrete.
11. Reduce the viscosity coefficient of concrete.
