molecular weight 220.15
Sodium gluconate is a white or light yellow crystalline powder, easily soluble in water, slightly soluble in alcohol, and insoluble in ether, which can be widely used in concrete as a retarder. Adding a certain amount of sodium gluconate to concrete can increase the retarding effect of concrete and delay the initial and final setting time of concrete.
range of application：
- Suitable for concrete, large-volume concreteandcast-in-place piles, constructed under hot temperature conditions;
- Suitable for slip-form construction concrete, pumping concrete, fly ash concrete, etc.;
- Configurable concrete grades of C15-C45.
- This product is non-toxic, non-flammable, stable in shape, and has no corrosion effect on steel bars;
- It has the effect of reducing water, improving the later strength of concrete, or increasing fluidity to save cement consumption;
- It can prevent cracks during summer construction and continuous pouring of concrete;
- Reduce the hydration heat of concrete and delay the occurrence of temperature peaks, reducing cracking caused by internal and external temperature differences.
- Convenient for construction and long-distance transportation
Determine the optimal dosage through trial mixing tests.
- Adjust the dosage after testing according to project requirements;
- Generally add it to the mixer simultaneously with the mixing water. The plasticizing effect is best if it is added with delay or added before concrete pouring and stirred slightly.
- To ensure the best use effect, it is recommended that before using this product for the first time or changing cement varieties in a project, users should conduct a trial mixing test to determine the optimal dosage and mixing method according to the specific conditions of the project.
