Description of sodium gluconate
Sodium gluconate is a kind of sodium polyhydroxy carboxylic acid, which is also known as sodium hydroxy caproate, which is white or light yellow crystalline granule or powder, easily soluble in water, slightly soluble in alcohol, and insoluble in ether. The product has good effect of retardation and high efficiency water reduction, and is widely used in construction, washing, food and medicine industry.
Sodium gluconate in concrete
1. With sodium gluconate, the W / C ratio can be reduced, which can increase the strength of concrete, which is a kind of high quality concrete.
2. Large blocks and large weight pouring projects are difficult to construct.
Due to the addition of sodium gluconate, the improvement of concrete workability and the delay of solidification time can avoid structural joints, which can improve the structural strength.
3. It is of great significance to improve workability by keeping the W / C ratio unchanged in hot areas.
4. The addition of sodium gluconate to the concrete mixture can delay the solidification time, which is very important for long and difficult pouring.
5. In the modern concrete industry, premixed concrete is prepared in the central location and transported by mixer trucks. in this case, it is very important to increase workability and initial setting time.
6. The concrete with higher strength and durability can be made by reducing w / c, and sodium gluconate can achieve this goal.
This is very important for high strength reinforced concrete.
7. Prefabricated masonry mortar must be used for a long time.
Adding sodium gluconate can prolong the working period.
8. It is difficult to operate cement slurry in oil well because of high temperature. After adding sodium gluconate, the concrete can work at 170 degrees Celsius for several hours.
Product characteristics of sodium gluconate
1. As cement setting retarder.
2. As water reducing agent.
3. Reduce the slump loss.
4. It is suitable for formulating concrete for hydraulic, marine, port, culvert, tunnel, bridge, road and other projects.
5.It is suitable for various mortars.
Product Precautions of sodium gluconate
1. This product is non-toxic and harmless, biodegradable, but not edible.
2. If it gets into the eyes, it should be rinsed with plenty of water in time.
3. If you cause allergies to part of the human body, you should consult a doctor in time.
