Description:
?
Sodium gluconate is a compound with formula NaC6H11O7. It is the sodiumsalt of gluconic acid.
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. Sodium gluconate is also a highly efficient set retarder and a good plasticiser / water reducer for concrete, mortar and gypsum.

Application In Concrete
1. Reduce 10 to 25% of cement content when the strength and the slump of the concrete are basically same.
2. It improves the initial slump of the concrete by more than 10cm, and the water-reducing ratio can reach 15 to 25 percent.
3. Has remarkable early strength and strengthening effects on the concrete, and improve the strength by 20 to 60 percent.
4. Improve the workability of the concrete and comprehensively improve the physical and chemical properties of the concrete.
5. Adapt to various cements well, and is well compatible with other types of 0s.
6. Particularly applicable to the following concrete projects: flowing concrete, plasticized concrete, steam-cured concrete, impermeable concrete, waterproof concrete, naturally-cured precast member concrete, reinforcing steel bars and prestressed reinforced concrete, high-strength and ultra-high-strength concrete.
