Gypsum retarder is a common additive in gypsum-based building materials, which can effectively prolong the construction open time. Most common retarder in gypsum has three types: organic acids and their soluble salts, alkaline phosphates and special retarders such as proteins. The organic acids and their soluble salts are mainly citric acid, sodium citrate, tartaric acid, potassium tartrate, acrylic acid and sodium acrylate, etc. Among them, citric acid and its salts are the most studied and the most effective. Citric acid and its salts can achieve a strong retardation effect when the dosage is very small.
