Product Description

Product Description

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.

Typical Properties
 

Appearance	White crystalline powder or granules
Assay%	99.5~ 100.5
Sulphated Ash (Residue on Ignition)	≤0.05
Loss on drying%	≤0.50
Heavy Metals(mg/kg)	≤5.0

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.
