Citric Acid as Admixature in Concrete China Manufacturer
Citric Acid as Admixature in Concrete Citric Acid (CA, also known as citric acid) is an important organic acid, which is colorless and odorless in appearance, has strong sour taste and is easily soluble in water. According to its water content, it is divided into citric acid monohydrate and anhydrous citric acid.

Admixtures for Concrete Countertops
• Simplifies mix design, compatible with most admixtures • Uses citric acid as a set retarder Heat • Temperature of curing concrete affects strength gain Concrete strength gain is about twice as fast at 90°F (32 °C) than it is at 70 °F (21 °C) Heat • Hot water Warms mix ingredients Decreases setting time Increases initial hydration rate

Retarding Admixtures Concrete Admixture
Retarders such as citric acid (sodium) and tartaric acid (potassium sodium) should not be used alone for lean concrete. 6. When the retarder containing carbohydrates is used in combination with the water reducing agent, the compatibility test can be carried out according to the method in Appendix A of this specification.
