CARBON FIBER-REINFORCED CONCRETE

摘要

In producing a pre-cast composite structure of a carbon fiber-reinforced concrete, an insulating layer having an electrical resistance of at least 100 ohms is formed on the surface of an iron member to which the concrete mix will come into contact, the iron-type metal member is placed on a predetermined position in the mold, the water and the concrete mix containing 0.2 to 10% by volume of carbon fiber are introduced into the mold, the molded composite structure is allowed to be partially hardened until it becomes capable of supporting itself, the composite structure which is partially hardened is parted from the mold, and is sufficiently hardened in an autoclave at a temperature of 100 to 215C.
