Applications of Sodium Gluconate CAS 527-07-1 in concrete
1. With sodium gluconate, the W / C ratio can be reduced, which can increase the strength of concrete, which is a kind of high-quality concrete.
2. Large blocks and large-weight pouring projects are difficult to construct.
Due to the addition of sodium gluconate, the improvement of concrete workability and the delay of solidification time can avoid structural joints, which can improve structural strength.
3. It is of great significance to improve workability by keeping the W / C ratio unchanged in hot areas.
4. The addition of sodium gluconate to the concrete mixture can delay the solidification time, which is very important for long and difficult pouring.
5. In the modern concrete industry, premixed concrete is prepared in a central location and transported by mixer trucks. In this case, it is very important to increase workability and initial setting time.
6. Concrete with higher strength and durability can be made by reducing w / c, and sodium gluconate can achieve this goal.
This is very important for high-strength reinforced concrete.
7. Prefabricated masonry mortar must be used for a long time.
Adding sodium gluconate can prolong the working period.
8. It is difficult to operate cement slurry in an oil well because of high temperatures. After adding sodium gluconate, the concrete can work at 170 degrees Celsius for several hours.
Product characteristics of sodium gluconate CAS 527-07-1
1. As cement setting retarder.
2. As a water-reducing agent.
3. Reduce the slump loss.
4. Sodium gluconate is suitable for formulating concrete for hydraulic, marine, port, culvert, tunnel, bridge, road, and other projects.
5. Sodium gluconate is suitable for various mortars.
Precautions of sodium gluconate CAS 527-07-1
1. Sodium gluconate product is non-toxic and harmless, biodegradable, but not edible.
2. If it gets into the eyes, it should be rinsed with plenty of water in time.
3. If you cause allergies to part of the human body, you should consult a doctor in time.
FAQs of sodium gluconate CAS 527-07-1
Q: How safe is sodium gluconate? Does it have any effect on human health?
A: Based on available scientific research, sodium gluconate is considered relatively safe for humans. The U.S. Food and Drug Administration (FDA) classifies it as one of the ingredients that is “Generally Recognized as Safe” (GRAS). This means that within reasonable limits of use, sodium gluconate does not pose an immediate health risk. However, like all chemicals, excessive intake may cause side effects such as digestive upset. For some sensitive individuals, contact with the skin may trigger a mild irritation reaction. Overall, when used in the right way, sodium gluconate is safe and reliable.
Q: How is sodium gluconate produced? Is the production process environmentally friendly?
A: Industrial grade sodium gluconate is mainly prepared by microbial fermentation. In this process, specific strains of bacteria will convert glucose into gluconic acid and then further react with lye to produce the corresponding sodium salt. This method is not only efficient but also environmentally friendly as it utilizes naturally occurring microbial metabolic activities and reduces the need for harmful chemicals. The modern production process also focuses on energy conservation and waste disposal, ensuring that the entire production process meets stringent environmental protection standards. In addition, due to its good biodegradability, sodium gluconate itself has a low environmental impact.
Q: Why is sodium gluconate chosen as an admixture in the concrete industry?
A: Sodium gluconate is an efficient water reducer and retarder in concrete formulation. It can significantly reduce the amount of water used in the concrete mix without affecting the fluidity, thus improving the strength and durability of the final product. At the same time, sodium gluconate delays the initial setting time of the cement, allowing the construction crew more time to complete the pouring and leveling operations, especially important in high temperature conditions. In addition, sodium gluconate provides better dispersion and more stable performance than the traditionally used lignosulfonate-based water reducers, making it the additive of choice for many construction projects.
Q: Can sodium gluconate replace other traditional cleaning and maintenance chemicals?
A: Sodium gluconate can indeed be an effective alternative to traditional cleaning and maintenance chemicals in certain application scenarios. For example, in metal surface treatment, it can be used in place of phosphate-based products for rust removal, degreasing and passivation, as sodium gluconate is effective in removing oxidized layers and preventing re-rusting. In household cleaning products, such as bathroom cleaners and dishwashing detergents, sodium gluconate can be used as a chelating agent to help soften the calcium and magnesium ions in hard water and enhance the cleaning effect. In addition, due to its mildness and low toxicity, sodium gluconate is particularly suitable for applications where user safety and environmental friendliness are important considerations. However, the exact replacement depends on the specific application needs and technical requirements, and sometimes it is necessary to combine with other ingredients to work together.
