  • Retarding admixture; advantages, types and appliions

     · The admixtures slow down the initial rate of hydration of cement or prolong the setting of cement paste in concrete. They are generally used to offset the accelerating and damaging effect of high temperature and to keep the concrete workable during the entire placing period which is sufficiently long. They are also used for grouting oil wells.
