Construction chemicals are admixtures that are used with concrete, cement, and other construction materials to provide additional durability and workability to various structures. Concrete admixtures can provide some beneficial effects on concrete. Such as accelerating condensation, slow curing, reducing water consumption, and increasing plasticity. Sodium gluconate is a white to tan granulated to fine crystalline powder. It is highly soluble in water. Sodium gluconate powder can be used as a concrete admixture in construction. It has the function of a water reducing agent and a retarder in concrete. Sodium gluconate concrete admixture is usually used alone, but it can also be used in combination with other retarders.

sodium gluconate benefits
As a concrete admixture, sodium gluconate has many benefits. It can reduce water consumption in concrete, improve the workability and strength of concrete. Moreover, adding sodium gluconate in 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.
Sodium Gluconate Uses in Concrete
1) 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. Improve the workability of concrete. When the water-cement ratio is constant, the addition of sodium gluconate can improve the workability of concrete.
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, the concrete water consumption can be reduced by 10%.
3. 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) 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, the time of concrete initial setting will be delay 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 the 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.
