摘要: The early age hydration by borate solution of three CSA cements containing, respectively, 0 %, 10 % and 20 gypsum weight cement was studied using isothermal calorimetry dynamic mode rheometry. XRD TGA analysis were carried out on pastes with increasing degrees (up to 90 days) specify the mineralogy figure mechanisms immobilization. It has been shown that retarding effect anions is due precipitation amorphous calcium C2B3H8; then incorporated in Aft-type phases. macroscopic properties hydrated binders (compressive strength, length change) also followed during 180 days.
