Pitch-based carbon fiber reinforced cements: structure, performance, applications, and research needs

Abstract

The improvements in the performance characteristics of cements due to carbon fiber reinforcement are described. In particular, the structure, the physical properties, the mechanical behavior, and the durability aspects of carbon–cement composites using pitch-based fibers are discussed. The various possible applications of these composites in structural and nonstructural applications are enumerated. The future research needs are identified. Key words: cements, carbon fibers, microstructure, strength, toughness, durability, applications.
