    Flexural behavior of cement systems reinforced with high aspect ratio aragonite micro-fibers

    This paper describes the synthesis of high aspect ratio aragonite microfibres using CaCl2 and Na2CO3 starting solutions and crystal growth using a seeding technique. The performance of these microfibres as reinforcement in portland cement paste matrices is verified. Microfibres in the context of cement science have been distinguished from larger macrofibres by an arbitrary limit in specific surface area (e.g. 200 cm2/g) or fibre length (< 6 mm). Cement composites with high volume fractions (>10 %) of these fibres can be produced with significant increases in strength and toughness relative to the unreinforced matrix.
