Description and advantages
-
Sodium gluconate, also known as the sodium salt of gluconic acid, is an organic substance with the chemical formula C6H11NaO7.
-
It is a white powder, non-toxic and good thermal stability.
-
Therefore it is very soluble in water, slightly soluble in alcohol, insoluble in ether.
-
Furthermore, sodium gluconate has always played an important role in many fields, such as construction industry, textile printing and dyeing, food industry, medical industry, electroplating and film manufacturing, etc.
-
Clearly, the prospects for its application are broad.
Applications
-
In the construction industry, sodium gluconate can be used as a concrete setting retarder and water reducing additive.
-
When a certain amount of sodium gluconate 98% min is added to cement, it can increase the ductility and strength of the concrete.
-
Furthermore, it can significantly slow down the initial and final setting time of concrete.
-
When the dosage is less than 0.15%, the logarithm of the initial setting time is proportional to the dosage.
-
That is, doubling the dosage slows the initial setting time by ten times, extending the operating time of the concrete.
-
This is especially important for long-term and difficult concrete pouring projects without affecting the final strength of the concrete.
Enhance work ability:
- When the water/cement ratio (w/c) is constant, adding sodium gluconate can improve the workability of concrete, act as a plasticizer, and improve the adhesion and resistance of concrete to stratification and water flow helps concrete have better slump.
Intensity boost:
- When the cement content remains constant, adding an appropriate amount of sodium gluconate to the concrete and reducing the water content (ie reducing the water/slag ratio) can increase the strength of the concrete to a certain extent.
Cement reduction:
- On the basis of maintaining the performance of concrete, sodium gluconate can be used as a cement reducing agent to reduce the amount of cement and reduce concrete production costs.
Good adaptability:
- Sodium gluconate has good adaptability to different types of cement and concrete mixing ratios.
- Whether conventional Portland cement, slag Portland cement or other special cement, can be effectively used with sodium gluconate to produce a stabilizing retarding effect. At the same time, for concrete of different strength grades, sodium gluconate can also be properly adjusted according to actual needs to meet the requirements of different projects.
