Zibo Jianhua Building Materials Co.,Ltd is one of the leading China anti-freezing concrete admixture manufacturers and suppliers with professional factory, welcome to buy or wholesale anti-freezing concrete admixture, polycarboxylate based antifreezing agent from us.
JH-D is a kind of early strength and antifreeze admixture which is compounded by JH series water reducing admixtures and various of effective materials. Main function: better early strength and anti-freezing, stable, can be widely used in all kinds of concrete construction in low temperature and in winter.
1. JH-D’s function: water-reducing, early strengthen, antifreeze etc. It can assure good workability of concrete and achieve the expected strength in a certain period of time, so that we ensure the concrete construction in low temperature winter.
2. Good adaptability in all kinds of cement and blending admixtures.
3. Low shrinkage, low viscosity and low bleeding rate of concrete: JH-D can significantly improve the stability, durability and workability of concrete.
4. Loss of freezing-thawing strength ratio ≤100％ at 50 times of concrete which is added JH-D.
5. Compressive strength ratio of concrete: Minus temperature: Maintainance 7 days.
Positive temperature : Maintainance 28days. (R-7+28) ≥120％
6. Extremely small content of chloride and alkali: has no corrosion on steel bars.
7. High stability: JH-D won’t precipitate out in low temperature.
8. Green and environmental protection: free from formaldehyde and other toxic substance.
9. Good economic returns: comprehensive cost of construction projects is low.
1. Optimal proportion and dosage is recommended before use according to the adaptive and temperature of engineering construction’s raw materials.
2. Compatibility test is recommended when use JH-D with other additives.
3. Precised dosage of JH-D is recommended to avoid repeat dosage, seep dosage and errors.
4. Good compatibility: JH-D can be used with polycarboxylate superplasticizer and pumping agent.
·Storage and Safety Matters
1. JH-D working environment: temperature -15—5℃. Keep out of sun, rain, impurity. Avoid evaporation of water.
2. JH-D’s quality guarantee period:180 days. Retest should be done when it is beyond validity, and can be used when it’s qualified.
3. JH-D is non-toxic, non-polluting and non-edible. Avoid touching with eyes and skin allergy people. If touching, should clear with water and timely go to see doctor.
