    摘要： A dry cementitious composition comprising, relative to the total dry weight of the cementitious composition, a) 4 to 80 wt.-% of cementitious binder, preferably Ordinary Portland Cement, b) 5 to 95 wt.-% of aggregates, wherein the aggregates have a grain size in the range of 0.001 mm to 8 mm, c) 0.005 to 5 wt.-% of carbon fibers provided with a sizing, preferably a polymer sizing, and/or in form of carbon fiber reinforced polymer lamellas.
    A preferred application of the cementitious compositions is grouting of wind turbine towers offshore or onshore. The invention also concerns the use of carbon fibers for the preparation of Ultra-High-Performance Fiber-Reinforced Grout (UHPFRG) or Ultra-High-Performance Fiber-Reinforced Concrete (UHPFRC).

    摘要： The present invention relates generally to a method of producing a fire-resistant gypsum board comprising a gypsum core, the method comprising providing a calcium sulfate slurry comprising a silicone oil having a hydride content of no more than 0.01 equivalents of Si-H per equivalent of silicon in an amount of 0.1 to 1 wt% of the mass of the gypsum core; allowing the calcium sulfate slurry to set; and drying the set gypsum material to provide the gypsum core. The invention also relates to a fire-resistant gypsum board comprising a gypsum core that shrinks by less than 6% by volume when heated to 850 °C, wherein the gypsum core comprises a silicone oil having a hydride content of no more than 0.01 equivalents of Si-H per equivalent of silicon, present in an amount in the range of 0.1 to 1 wt% based on the mass of the gypsum core.
