Abstract: Non-fractured, non-fibrillatable short fibers, for reinforcing matrix materials such as concrete, have substantially uniform transverse cross-sectional areas along their length for maximum efficiency in pull-out resistance, and two different tapering characteristics along their lengths. Preferred bi-tapered fibers of the invention have a high modulus of elasticity in the range of 5-250 Gigapascal and are preferably modulated in both tapering dimensions. Matrix materials containing the fibers, as well as a method for making the fibers, are disclosed.

Abstract: Synthetic polymer reinforcing fibers provide dispersability and strength in matrix materials such as concrete, masonry, shotcrete, and asphalt. The individual fiber bodies, substantially free of stress fractures and substantially non-fibrillatable, have generally quadrilateral cross-sectional profiles along their elongated lengths. Preferred fibers and matrix materials having such fibers demonstrate excellent finishability in addition to dispersion and toughness properties.

Abstract: The invention relates to fiber compositions that can be pumped and metered in the fashion of fluid chemical admixtures into a concrete mix, thereby enabling the fibers to be dispensed by concrete ready-mix plant operators who can provide verification of fiber administration and dosage. The fibers, particularly plastic shrinkage control fibers having large cumulative surface area, are suspended in an aqueous medium such that their surface area is already wetted out, thereby virtually assuring that substantial uniform fiber dispersion can be achieved without clumping and the delay that is usually required by fiber intermixing.

Abstract: Exemplary liquid cement additive compositions have high solids loading which includes alkali or alkaline earth metal salts and other cement additive components. The liquid carrier is preferably aqueous in nature, although non-aqueous carriers are possible, and the carrier is modified using a viscosity modifying agent and dispersant to help load salt and other solids in high level amounts. Thus, methods for making the liquid cement additive compositions are also disclosed.
