What is the principle of concrete retarder? Is there any relationship between retarding time and temperature?

Retarder, Retarder, is an admixture that delays the setting time of concrete without significantly affecting the later strength. The main ingredients are polyhydroxy compounds, hydroxycarboxylates and their derivatives, and high-sugar lignosulfonates. Because they also have water-reducing properties, they are also called retarding water-reducing agents. In addition, some inorganic salts such as zinc chloride, borate, and…
