In concrete engineering, the addition and use of sodium gluconate is very popular. In the process of concrete configuration, adding an appropriate amount of sodium gluconate to cement can reduce water consumption, enhance the plasticity and strength of concrete and improve the service time of concrete. The main effect of sodium gluconate mixed into concrete is the function of water reducer and corrosion inhibitor. The specific application effect is analyzed as follows:
1. Adding sodium gluconate can reduce the ratio of water and cement, reduce the production cost, improve the strength of concrete, and make high-quality concrete with higher strength and durability.
2. When the specific ratio remains unchanged, adding less than 0.1% sodium gluconate can play the role of plasticizer and improve the workability. The specific improvement degree is directly proportional to the addition amount. Especially in hot areas, it is of great significance.
3. When the cement content remains unchanged and the water content decreases, the strength can be improved. The specific standard is that when the addition of sodium gluconate is 0.1%, the amount of water can be reduced by 10%.
4. When reducing the content of water and cement at the same time, under the condition that the ratio of them remains unchanged, sodium gluconate is used as cement reducer.
5. In the large and heavy grouting projects which are difficult to construct, sodium gluconate can avoid the interface on the structure and improve the structural strength by improving the setting time and working performance.
6. Adding sodium gluconate to the concrete mixture can delay the setting time, which is very important for long-time construction and difficult pouring. At the same time, it adapts to the working mode of transporting ready mixed concrete to the construction site in the current concrete project.
7. The use of gluconic acid can make the prefabricated masonry mortar used for a long time and prolong the working period.
8. It is difficult to construct the concrete pouring project in the high temperature environment. Due to the high temperature and difficult operation of oil well pouring cement, adding grape sodium carbonate can make the concrete work for several hours at the high temperature of 170 ℃.
The above is a summary of the role of sodium gluconate in concrete engineering. I hope it can help you understand sodium gluconate and facilitate its use in future operations. At the same time, we should also understand the specific use standards of sodium gluconate, which should not be used blindly, and do a good job in engineering and construction on the basis of ensuring the production safety of the industry.
