Citric Acid Anhydrous
CAA-99
Chemical Nature
Anhydrous citric acid is colorless translucent crystal or white fine powder crystal, odorless, with strong sour taste. Citric acid has obvious retarding effect on concrete, and the content in concrete is usually 0.03%~0.10%. When the dosage is 0.05%, the strength of 28d concrete is still improved, and the strength will be weakened by increasing the dosage. The addition of citric acid can slightly change the gas content of concrete and improve the frost resistance of concrete.

Features of application
1, it has a retarding effect on concrete, delaying the initial and final solidification time of concrete;
2, It has a retarding effect on gypsum based products, delaying the initial and final solidification time of gypsum;
3, in the self-leveling mortar products, the combination of citric acid and casein has better retarding effect. ;
4, convenient summer concrete construction and long-distance transportation.
Storage
The product should be stored in a dry, clean environment, in its original packaging and away from heat sources. This product is not easy to fail, but it is a hydrophilic product, if the storage environment is poor, it will slowly inhale water, it is recommended to follow the principle of first in first out when using. If the product is not used up, the packaging must be tightly sealed to prevent moisture intrusion.
