  • Calcium ferroaluminate compound, cement admixture and its manufacturing methods, and cement composition
    Patent number: 8425679
    Abstract: It is the object of the invention to provide a cement admixture, and a cement composition that can impart good enough rustproofness to reinforcing bars in hardened cement concrete, and can have resistance to penetration of chloride ions entering from the outside, prevent the hardened cement concrete from getting porous due to reduced leaching of Ca ions and have a self-recovery capability. The invention provides a cement admixture characterized by containing a calcium ferroaluminate compound comprising a CaO—Al2O3—Fe2O3 system, and having a Fe2O3 content of 0.5 to 15% by mass and a CaO.2Al2O3 structure with a CaO/Al2O3 molar ratio ranging from 0.15 to 0.7.
    Type: Grant
    Filed: November 25, 2010
