Sodium gluconate is used as concrete retarder admixture
Sodium gluconate, also known as the sodium salt of gluconic acid, is an organic substance with the chemical formula C6H11NaO7. It is a white powder, non-toxic, and good in thermal stability. So it is very soluble in water, slightly soluble in alcohol. Moreover, sodium gluconate always plays an important role in many fields, such as construction industry, textile printing and dyeing, food industry, medical industry, electroplating and film manufacturing and so on. Obviously, its application prospect is very broad.
As we all know, sodium gluconate powder can be widely used in different industries, such as concrete, soap, food, medical, cosmetics, toothpaste, etc.

sodium gluconate is a versatile solution for the construction industry, serving as both a concrete retarder and water reducing admixture. By adding a precise amount of sodium gluconate 98% min to cement, the plasticity and strength of the concrete can be enhanced. This admixture also provides the added benefit of delaying the initial and final solidification time of the concrete.
(1) Used as concrete retarder admixture. It can delay the setting time of concrete, moreover, it can extend the working time of concrete from a few hours to a few days without compromising strength. When you need to place concrete for a long time or the weather is hot, this is an advantage. In a word, sodium gluconate retarder has many advantages in the construction industry.
- Using sodium gluconate can be reduce the Water to Cement (W/C) ratio, so it increases the strength of the concrete and forms a high-quality concrete.
- Large and heavyweight perfusion construction engineerings are very difficult. Due to the addition of sodium gluconate, the operability of concrete is improved, the setting time is delayed, the contact surface can be avoided on the structure, and the structural strength can be improved.
- Adding sodium gluconate to the concrete mixture can delay the setting time, this is so important for long or difficult perfusion.
- In the construction industry, the pre-mixed concrete is made at a central location and delivered by a mixer truck. In this case, it is important to delay the initial solidification time of concrete.
- Oil well grouting is difficult to operate due to high temperatures. But after adding sodium gluconate powder, the mud can work at 170℃ for several hours.
(2) Used as water reducing admixture. It can reduce the mixing water consumption of concrete and increase the strength of concrete while maintaining the consistency of concrete, cement dosage and slump. The water to cement ratio (W/C) is constant, in this case, sodium gluconate can improve concrete workability. While the cement content remains the same, it can reduce the water content in the concrete. When the amount of sodium gluconate added is 0.1%, the amount of water added can reduce by 10%. What’s more, sodium gluconate can reduce cement content and save costs for you.
Packaging and storage
1,Powder products are made of chemical fiber woven bags, lined with plastic film bags, each bag net weight (25+0.2kg), can also be customized according to customer requirements.
2,,powder products should be stored in dry and ventilated special warehouse, products such as damp caking can be crushed or dissolved into water agent use, will not affect the use effect.
