Shandong Wanshan Chemical Co., Ltd is a whole owned subsidiary of Shandong Wanshan Group Co., Ltd. As an ISO 9001:2008 certified firm, Shandong Wanshan Chemical Co., Ltd is a well-known manufacturer of Sodium Gluconate in China.
Sodium Gluconate has a wide range of applications.
1) Sodium Gluconate could be used in the food industry. Sodium gluconate can replace salt and improve food flavor.
2) Sodium Gluconate could be a chelating agent in the construction, textile, metal surface dealing, and water treatment.
3) Sodium Gluconate could be the cleaning agent for the steel, and glass.
4) Sodium Gluconate could be the electroplating industry aluminum oxygen coloring agent.
5) Sodium Gluconate could be the high-efficiency concrete retarder & concrete superplasticizer in the concrete industry.
1) Sodium Gluconate Set Retarder in Concrete
Sodium gluconate for concrete can significantly delay the setting time of concrete. When the amount of sodium gluconate is 0.15% or less, the amount of sodium gluconate in concrete is double, and the time of concrete initial setting will be delayed by ten times. This prolongs the work time of concrete from a few hours to a few days without losing its strength.
Nowadays, the concrete in many places is transported to the construction site after mixing in the plant area. If the concrete solidifies during this period of time, the construction will not be carried out. At this time, it is necessary to add sodium gluconate admixture to the concrete. Because it can retard the concrete and enhance its plasticizing performance of the concrete.
In addition, due to the large volume of the infusion project, it is difficult to construct. Adding sodium gluconate to concrete can improve the working performance of concrete and delay the setting time of concrete. Thus avoiding the formation of joints on the structure and improving the structural strength. That is conducive to the implementation of large-volume perfusion projects.
2) Sodium Gluconate as Water Reducer
As a water-reducing agent, sodium gluconate can make concrete mixes have better processability and increase concrete slump. By adjusting the water-cement ratio and adding sodium gluconate, the strength of the concrete structure can be enhanced. Besides, the cement content can be reduced while maintaining the original strength of the concrete. By adding sodium gluconate to the concrete, you can get the following results:
1. Reduce cement and water. The addition of sodium gluconate can reduce the cement content to the same proportion of water consumption. The overall water-cement ratio of the concrete remains unchanged.
2. Improve the strength of concrete. When the cement content remains constant and the water content of the concrete decreases. With 0.1% sodium gluconate added, concrete water consumption can be reduced by 10%.
3. Improve the workability of concrete. When the water-cement ratio is constant, the addition of sodium gluconate can improve the workability of concrete.
As a concrete admixture, sodium gluconate has many benefits. It can reduce water consumption in concrete, and improve the workability and strength of concrete. Moreover, adding sodium gluconate to concrete can delay the concrete setting time and improve freeze-thaw resistance. If according to the water-cement ratio, temperature, and some other reasons to add sodium gluconate in concrete, then it can delay the concrete setting time to more than 16 hours. Because it acts as a corrosion inhibitor, it helps to protect the iron rods used in concrete from corrosion. Last but not least, sodium gluconate in concrete can reduce bleeding, segregation, dry shrinkage, and cracking.
