WebbRetarders do not reduce the exotherm or the peak temperature of mass concrete. They only delay the onset of the exotherm. The only effective way to control exotherm is by the use of less reactive binders such as pfa or ggbs. Chilled mixing water or cooling the aggregate are also effective ways of reducing the peak temperature. WebbSet retarder refers to the admixture that can delay the setting time of concrete mixing materials, and have no bad impact on the development of concrete’s latter strength. It often contains lignosulfonate, carbohydrate, inorganic salts and organic acids. The most common ones are calcium lignosulfonate and molasses.
