APPLICATION OF SHORT CARBON-FIBER IN CONSTRUCTION

Recent developments of short carbon fiber reinforced concretes are briefly summarized. A variety of commercial applications has been made since the first large scale construction in 1984. In spite of a high reinforcing fiber cost at the present time, usages are found in many special applications where the superior characteristics of carbon fiber are needed. The current construction usage for special concretes require light weight, long term durability, erosion resistance, low abrasion, low permeability, or electromagnetic shielding. The applications for reinforced concretes are expected to multiply due to decreased manufacturing cost of the fiber, and increased saving from a reduction time for construction. Possible future reinforcements by carbon fiber or hybrid fibers can be extended to include low cost ceramics
