  • Patent number: 9212092
    Abstract: The claimed subject matter relates to a novel cement comprising Portland cement clinker and a supplementary cementitious material. The supplementary cementitious material comprises a heat treated clay material and an optionally heat treated carbonate material, wherein the clay material has been heat treated optionally together with the carbonate material in such a way that the heat treated clay material is substantially dehydroxylated while the optionally heat treated carbonate material remains substantially carbonated. This can be achieved by premixing the carbonate and clay materials before heat treating to 400-700 C, or heat treating the clay material separately to a temperature of up to 900 C. When used in the final application the cement results in much higher strengths than would be predict from any other combination of these materials.

  • Patent number: 8337612
    Abstract: Disclosed are a system, a method and/or composition of environment friendly composite construction material. In one aspect, a method includes providing a mixture of a pozzolanic material and/or a kaolin clay with an activator solution to form an alumino-silicate cementitious material through a resulting geo-polymerization process. The alumino-silicate cementitious material is in the form of a paste. The method also includes processing the alumino-silicate cementitious material to transform the alumino-silicate cementitious material that is in the form of the paste to a form of a powder of the alumino-silicate cementitious material. The method further includes mixing the alumino-silicate cementitious material which is in the form of the powder with water to control a workability of the alumino-silicate cementitious material.

  • Publication number: 20120318172
    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.

  • Publication number: 20120255463
    Abstract: A low-pressure method for producing construction materials, such as blocks, bricks or slabs, utilizing high percentages of waste cement dust in admixture with additive material capable of effectively neutralizing the high lime content and agglomerating the extremely fine particles of the cement dust upon blending of the admixture with water. The resulting blend may simply be cast in molds of various shapes and sizes and cured under normal atmospheric pressure conditions into a hardened construction material exhibiting high strength, light weight and high thermal insulation.
