Sodium gluconate is frequently used in concrete and cement to slow down the setting time. Sodium Gluconate improves the overall compressive strength of cement at 3 and 28 days, delays setting, and increases the fluidity of cement mortar.

Sodium gluconate, which is also known as Sodium Salt of Gluconic Acid, occurs from fermenting glucose. The appearance is a light yellow or white crystal powder. It is highly soluble when placed in water, yet it is insoluble when placed in alcohol. It also has a saline taste, and it is readily biodegradable, non-corrosive, and non-toxic. As one of the essential chemical admixtures, sodium gluconate is used as a water-quality stabilizer, acid-base equilibrium, a retarder, cement-blending agent, and surface-cleaning agent and is used widely in many other fields, including oil drilling, the textile and cleaning industry, and concrete.

The Main Uses Of Sodium Gluconate

  • Retarder Agent For Concrete

Sodium gluconate is used to improve the strength and workability of concrete and is also used as a retarder for concrete across many of the construction sectors. Adding specific amounts of this additive to cement prolongs the curing and starting time of concrete or cement, which means it delays the final and initial setting time of the concrete without impacting the strength. Sodium Gluconate can also prolong the “working time” of cement or concrete. It is usually used in combination with some concrete water reducer.

  • Steel Surface Cleaning Agent

When it comes to specialized applications where the steel surface has to be cleaned stringently to ensure the cladding materials bond tightly to the surface of the steel sodium gluconate can be used as an effective cleaning agent for cleaning the steel’s surface due to its effective cleaning effect.

  • Water-Quality Stabilizer

Sodium Gluconate is also used widely as one of the water stabilizers in low-pressure boilers, and cooling-water systems, among other fields. Of course, phosphates products(such as shmp chemical, stpp) are still one of the commonly used descaling agents for boiler water treatment. In comparison to general corrosion inhibitors, as the temperature increases so do its corrosion-inhibition abilities.


  • Textile Industry

Sodium Gluconate is also commonly used for degreasing and fiber cleaning. It can improve the bleaching effects relating to certain bleaching powders and the uniformity of color in dyes and improve the dyeing hardening degree of raw materials in the textile industry.

  • Glass Bottle Cleaning Agent

Sodium Gluconate can also be used to effectively remove the rust that accumulates around the mouth of bottles and to remove the labels on the outside of bottles. It also decreases the likelihood of the washer nozzle or the pipeline plugging. It is essential that it doesn’t affect environmental safety or food.

  • The Petroleum Industry

Sodium Gluconate is also a common agent used in the production processes of oil-field drilling fields along with petroleum products.


Sodium Gluconate is typically used alone, yet it can also be mixed with other retarders like phosphates-of-carbohydrates in use. Sodium Gluconate comes in crystalline form and is made in properly-controlled environments. This is one of the pure chemical, non-corrosive compounds, which means the quality is consistent. This is the feature that guarantees the applications of reproducible and reliable results.
