Sodium gluconate can be used as high-efficiency chelating agent in construction,textile printing and dyeing, metal surface treatment and water treatment industries, steel surface cleaning agent, glass bottle cleaning agent, aluminum oxide coloring � in electroplating industry, and high-efficiency retarder in the concrete industry. Industrial sodium gluconate used as concrete admixture has the following advantages: 1. With sodium gluconate, the W/C ratio can be reduced, which can increase the strength of concrete. This is a high-quality concrete. 2. It is difficult to construct large blocks and heavy weight. Due to the addition of sodium gluconate, the improvement of concrete workability and the delay of setting time can avoid the formation of joints on the structure, and as a result, the structural strength can be improved. 3. It is of great significance to keep the W/C ratio constant and improve workability in hot areas. A large amount of sodium gluconate was used when building bridges in the Middle East. 4. Adding sodium gluconate to the concrete mixture can delay the setting time, which is very important for long and difficult perfusion. 5. In the modern concrete industry, ready-mixed concrete is prepared at a central location and then transported by mixer truck. In this case, it is very important to increase workability and initial setting time. 6. Lowering the W/C ratio can make concrete with higher strength and durability. Sodium gluconate can achieve this goal. This is very important for high-strength reinforced concrete. 7. The prefabricated mortar for masonry must be usable for a long time. Adding sodium gluconate can extend the working period. 8. Oil well grouting grout is difficult to operate due to the high temperature, but after adding sodium gluconate, the concrete can work at 170 for several hours.
