Important use of sodium gluconate in the construction industry

Sodium gluconate is widely used in construction, textile, printing,dyeing industries and so on. Today we want to know the effect of sodium gluconate in construction industry.
When a certain amount of sodium gluconate is added to the cement, it will have a very good effect on the concrete, which not only increases the plasticity and strength of the concrete, but also has a retarding effect, it means delays the initial and final solidification period of the concrete.
For example, adding 0.15% sodium gluconate can extend the initial solidification time of concrete by more than 10 times, that is, the plastic plasticizing time is extended from several hours to several days ,not affecting its fastness.
Plasticity and delaying the initial solidification time are very important issues in concrete operations.
For example,in high temperature season.construction and big engineering operations,delaying the initial solidification time is a problem,sodium gluconate can solve this problem satisfactorily.
In addition to this, it is difficult to glue the oil well at high temperature. The concrete that adding sodium gluconate can be molded in a few hours at a high temperature of 170 °C.Finally,this problem can be solved.
