Sodium Gluconate

Sodium gluconate is the sodium salt of gluconic acid, produced by fermentation of glucose. It is a white to tan, granular to fine, crystalline powder, very soluble in water. Non-corrosive, non-toxic and readily biodegradable (98 % after 2 days), sodium gluconate is more and more appreciated as a chelating agent.
The outstanding property of sodium gluconate is its excellent chelating power, especially in alkaline and concentrated alkaline solutions. It forms stable chelates with calcium, iron, copper, aluminium and other heavy metals, and in this respect, it surpasses all other chelating agents, such as EDTA, NTA, and related compounds. Concrete Admixture
Sodium gluconate is used as a water-reducing agent and retarder in concrete engineering.Its water-reducing, plasticizing, retarding effect is very significant, can greatly improve the workability of concrete, reduce slump loss, improve the later strength of concrete, as retarding agent can make the initial setting time from a few hours to a few days without damage strength.And a wide range of applications, pumped concrete, large flow concrete, mass concrete, high strength concrete can be used.
