Durability of Bittern-Resisting Cement in High Concentration Brine

Abstract:

Article Preview

Bittern-resisting cement (BR) has more excellent performance to resist physical attack and chemical corrosion in high-concentration brine environment than ordinary Portland cement or sulfate- resisting Portland cement. The durability and chemical stability of bittern-resisting cement are studied under drying-wetting cycles in brine, the microstructure and chemical component of hydration products also are determined by SEM/EDXA. The corrosion resistance coefficient Kf of BR mortar prisms in high-concentration brine for 6 months is over 96%, and the mass loss of mortar prisms after 30 drying-wetting cycles in brine is only 4.3%. SEM/EDXA analysis shows that the microstructure and chemical composition of BR hydration products exposed to high-concentration brine environment is more densely and stable than those of ordinary Portland cement.
