A fixed construction (10) comprises an under layer (12) and an upper layer (14) which is poured upon the under layer (12). The under layer (12) is a floor (to be renovated) of concrete or of asphalt. The upper layer (14) is a renovation layer. The upper layer (14) comprises high-performance concrete (pressure strength > 80 MPa) which is reinforced by a combination of fibers (22) and of steel rods (24) with a yield strength higher than 650 MPa. |
