Admixtures for concrete
Description:
The sodium gluconate is polyhydroxy sodium carboxylate, it is also called sodium pentahydyoxycaproate, the molecular formula is C6H11O7Na, the molecular weight is 218.14, and it is white or light yellow crystalline particles or powder in appearance, easily soluble in water, slightly soluble in alcohol, and insoluble in ether. It is mainly used for acid-base balance agents, water quality stabilizers, surface cleaners, cement admixtures and so on, with wide application.
Application:
1. Used as a water quality stabilizer.
2. Used as a steel surface cleaner
3. Used as a cement admixture: After a certain amount of sodium gluconate is added into the cement, it can improve the plasticity and strength of the concrete, and has retardation effect, namely postpone the initial and final setting time of the concrete.
4. Can be used for industrial fields such as electroplating, film manufacturing and so on.
