Sodium Gluconate also known as a gluconic acid’s sodium salt, which is a prominent material used in multiple industries. It’s a crystalline, granular white solid that is soluble in water. It’s renewable, biodegradable, non-toxic, and non-corrosive. Moreover, it is also efficient concrete plasticizer/water reducer.
One of the most significant properties of Sodium Gluconate is its superior chelating power, particularly in concentrated alkaline and alkaline solutions.
Sodium Gluconate in Construction Industry:
One of its significant roles in the construction industry is its function as a water reducer. Here are some of the key benefits of using Sodium Gluconate in concrete mixtures:
Improved workability:
Sodium Gluconate powder is used as a concrete admix. Sodium gluconate enhances the workability of concrete, making it easier to handle and apply.
Lowering water content:
Sodium Gluconate helps in reducing the water content in the concrete mix without affecting its workability.
Reduced dry shrinkage:
Sodium Gluconate helps in reducing the dry shrinkage of concrete, thus preventing cracking and bleeding.
Increased Strength:
By adding Sodium Gluconate to the mix, the strength of the concrete can be increased.
Retarding Setting Times:
Sodium Gluconate can delay the setting time of cement. This is particularly beneficial for long-time and difficult pouring.
Enhanced Durability:
Reducing the water-cement ratio can make the concrete have higher strength and durability, which can be achieved by Sodium Gluconate.
Other Industrial Uses:
Corrosion Inhibitor:
- Sodium Gluconate also works as a corrosion inhibitor, protecting iron bars in concrete from corrosion. By adding sodium gluconate to the mix, the strength of the concrete can be increased. When the amount of sodium gluconate added is 0.1%, the amount of water added can be reduced by 10%.
Other Uses:
- Sodium Gluconate has an amazing property of mixing with trivalent and di-trivalent metal icons, like aluminium (Al) , copper (Cu) and more which removes them from water or any solution at alkaline pH, without affecting the temperature. This property makes it a vital ingredient in metal surface treatment, bottle washing, and water treatment.
- Due to its various functionalities, Sodium gluconate is a usual ingredient in industrial and household cleaners. It works as a redeposition agent, builder, sequestering agent, and a chelating agent.
- In alkaline cleaners, like detergents, degreasers etc., Sodium gluconate prevents hard water ions from mixing with alkalis by allowing the cleaner to work to its maximum capability.
- Sodium gluconate protects metals which includes stainless steel, from caustic based cleaners.
Handling and Storage Requirement of Sodium Gluconate:
- Handling Precautions
- When handling Sodium Gluconate, it’s important to wear personal protective equipment and face protection. Ensure adequate ventilation to avoid inhalation of dusts. Avoid contact with skin, eyes or clothing. Avoid ingestion and inhalation. Avoid dust formation.
- Storage Conditions –
- Store Sodium Gluconate in a cool place. Keep the container tightly closed in a well-ventilated dry place.
- First Aid Measures –
- In case of exposure, the following first aid measures are recommended:
- Inhalation: If inhaled, move the person into open space for fresh air. If not breathing, give artificial respiration.
- Skin Contact: Wash off with soap and plenty of water.
- Eye Contact: Flush eyes with water as a precaution.
- Ingestion: Never give anything by mouth to an unconscious person. Rinse mouth with water.
Are there any environmental impacts associated with the use of sodium gluconate?
No, Construction Grade Sodium Gluconate, chemical, is known for its multifunctional properties and There are no environmental impacts associated with the use of Sodium Gluconate.
Biodegradability
One of the key environmental benefits of Sodium Gluconate is its biodegradability. This means it can break down naturally in the environment. It is considered environmentally friendly.
Non-Toxic
Sodium Gluconate is considered non-toxic. This means it does not pose a risk to human health or the environment when used appropriately.
Water Solubility
Sodium Gluconate is soluble in water. This means it will likely be mobile in the environment due to its water solubility.
Ecotoxicity
Sodium Gluconate does not pose ecotoxicity risks. It should not be emptied into drains, but if it does enter the water system, it does not pose a significant risk to aquatic life.
Conclusion:
Sodium Gluconate is a game-changer in the construction industry. Its multifunctional properties and versatility make it an ideal choice for enhancing the quality and durability of construction projects. The production of Sodium Gluconate involves a series of intricate steps, each crucial in ensuring its quality and effectiveness. Notably, it plays a significant role as a water reducer, improving workability and strength while reducing cement content. This extends to its use in concrete mixtures, where it enhances quality, durability, and acts as a corrosion inhibitor. Despite its extensive benefits, it’s important to handle Sodium Gluconate with care, taking necessary precautions to ensure safety. Moreover, it stands out for its minimal environmental impact due to its biodegradability, non-toxic nature, and lack of ecotoxicity, making it a sustainable choice for construction projects.
