Product Description

Anhydrous citric acid is colorless translucent or white fine powder crystals, odorless, and has a strong sour taste. Citric acid has an obvious retarding effect when used in concrete. The dosage in concrete is usually 0.03%~0.10%. When the dosage is 0.05%, the strength of the concrete is still improved after 28 days, and continuing to increase the dosage will weaken the strength. Adding citric acid slightly changes the air content of concrete and improves the frost resistance of concrete.

1. It has a retarding effect on concrete and delays the initial and final solidification time of concrete;
2. It has a retarding effect on gypsum-based products, delaying the initial and final setting time of gypsum;
3. Among self-leveling mortar products, the combination of citric acid and casein has a better retarding effect. ;
4. Convenient for summer concrete construction and long-distance transportation.
Store products with original packaging in a dry, clean environment and away from heat sources. This product is not easy to lose efficacy, but it is hydrophilic-based. If the storage environment is poor, it will slowly absorb moisture. It is recommended to follow the first-in-first-out principle when using it. The packaging must be tightly sealed to prevent moisture intrusion if not finished use.
