Set Retarder(Sodium Gluconate)
Sodium gluconate is suitable to apply in high temperature season, long distance transportation, and pump concrete; also
appropriate for mass concrete, self-leveling concrete and high strength high performance concrete, etc.
Sodium has the important effects for maintaining the osmotic pressure, regulating the acid-base balance in human body and developing the normal functions of the verves and muscles. The product is able to prevent effectively sodium-deficit syndromes from occurring. It is a good food additives or food fortifier of sodium.
