Title: Fiber Matrix Compatibility Consideration in Fiber Reinforced Cements and Concretes
Author(s): Collin D.Johnston
Publication: Special Publication
Appears on pages(s): 249-270
Keywords: Compatibility; methods; durability; fibers; manufacturing matrix methods;
Abstract:General concepts governing the interaction of fibers with paste, mortar and concrete matrices are presented for the freshly mixed and hardened states in the context of the need to reconcile these often conflicting interactions to produce useful composites. Problems and limitations arising from the addition of fibers are discussed in terms of fiber amount, material type, form (monofilament, multifilament, bundled, etc.), geometry and compatibility with the manufacturing process fi-om mixing to final consolidation in the freshly mixed state. Fiber-matrix compatibility considerations are also identified for the hardened state with respect to their importance for short-term and particularly sustained long-term property enhancement. Long-term performance is highlighted for circumstances where chemical incompatibility of fibers and matrix may lead to gradual deterioration in initially very satisfactory early-age properties.
