Citric Acid
-
Citric Acid is a set retarder commonly used in concrete admixtures. It works with Tartaric Acid by forming complexes with the calcium ions in the cement, which reduces the availability of these ions for the chemical reactions that cause concrete to set.

Citric Acid is a weak organic acid commonly used in construction applications to improve the setting time of cement-based products. Citric Acid is beneficial in hot weather conditions where the rapid setting of the mortar can cause cracking and other issues. Citric Acid also improves the workability and pump ability of Dry-mix (pre-bagged) systems, making it easier for contractors to apply.

Citric Acid is a weak organic acid that can be used as a retarder additive in gypsum products. It can help slow down the gypsum’s setting time and improve its workability during production.

Citric Acid is an organic acid, like gluconic Acid and can act as a strong set-retarding agent in oil well cementing applications. These acids can chelate with the metal ions in the cement, which slows down the hydration process and extends the setting time of the cement. This is useful in situations where a longer setting time is desired, such as when a cement slurry needs to be pumped over a long distance or when there is a need for a delayed set.
The set-retarding effect of organic acids can be influenced by factors such as temperature, pH, and concentration. At higher temperatures, the retarding effect may be reduced, while at lower pH levels or higher concentrations, the retarding effect may be enhanced. Therefore, careful consideration of these factors is necessary when using organic acids as set-retarding agents in oil well cementing applications.
