Title:
CARBON-FIBER-CONTAINING CONCRETE OR MORTAR COMPOSITION, CARBON-FIBER-REINFORCED CONCRETE OR MORTAR STRUCTURE, AND PRODUCTION METHOD THEREFOR
Document Type and Number:
WIPO Patent Application WO/2023/181605
Kind Code:
A1
Abstract:
Purposes of the present invention are to provide a carbon-fiber-containing concrete or mortar composition which has excellent handleability due to a reinforcement produced from precut raw-material carbon fibers, such as short fibers, scrap fibers resulting from processes, or carbon fibers reclaimed from CFRPs, etc., and to provide a carbon-fiber-reinforced concrete or mortar structure which is a cured object formed from the carbon-fiber-containing concrete or mortar composition and in which the fibers have a high reinforcing effect. This carbon-fiber-containing concrete or mortar composition includes carbon-fiber masses each configured at least from carbon fibers and a binder, and is characterized in that the carbon-fiber masses each have the shape of a spindle.
