Concrete Retarder Tataric Acid L+ White Granular Retarding Agent Concrete Chemical Admixtures
Concrete retarders slow down the hydration process.
This keeps the concrete in its plastic stage and more workable for longer.
Concrete retarders are used when more time to place the concrete is needed during transportation or a complex placing condition.
L-(+)-Tartaric acid, or "natural" tartaric acid, is abundant in nature, especially in fruits. Its primary commercial source is as a byproduct of the wine industry. It is used as an additive in many foods, such as soft drinks, bakery products, and candies. Industrial uses include tanning, ceramics manufacture, and the production of tartrate esters for lacquers and textile printing.
