Abstract

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).
