Basalt Fiber Composite Reinforcement for Concrete

摘要

This project explored the feasibility of using rebars made from braided fiberstrands as concrete reinforcement. The basalt fibers were produced using a process developed in Ukraine. Continuous basalt fibers, 9-15 um in diameter, were determined to be most suitable for rebar fabrication. The rebards consist of about 80-90% fibers and an organic binder. Tests results for mechanical properties (strength and modulus) appear to establish the suitability of basalt composite rebards for use as concrete reinforcement.
