  • Concrete Retarders: Types, Uses , Advantages &

    Concrete retarders may be used with water to avoid cracks and bleeding. Depending on its water-cement ratio, cement content, and the amount of C3a in the cement, the dose of retarder admixture should be within the limit. Concrete retarders can undergo variable action on different types of cement when used in varying quantities.

  • Set Retarders - an overview | ScienceDirect Topics

    It is very necessary to make studies of the application of PG without impurities in cement production. The PG has a low content of CaO and CaCO 3 but higher than the values presented in NG; therefore its use in cements is indicated to adjust the setting process as retarder, that is, performing the function of NG in the manufacture of cements.
