  • Publication number: 20220017421
    Abstract: Provided is a structure having both fire resistance and heat insulation properties and capable of retaining its shape without being collapsed or deformed even when exposed to a flame. The present invention provides a fire-resistant heat-insulation composition comprising 70 to 250 parts by mass of gypsum based on 100 parts by mass of calcium aluminate having a CaO content of 34% or more, and 0.1 to 20 parts by mass of a fibrous inorganic clay mineral having a crystallization water ratio of 5% or more, based on 100 parts by mass of the total of the calcium aluminate and the gypsum.

  • 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.
