Abstract (en)
[origin: WO9726395A1] A yarn for use in a cement mortar matrix, includes a core (22) and a multitude of staple fibers (26) forming a layer which envelopes the core (22) and provides an extended surface area and interstical spaces for infiltration by cement fines and hydrates. The staple fibers (26) are spun around the core (22) and attached to the core (22) at spaced areas (30). The staple fibers (26) also have sufficient freedom of radial movement to provide the interstical spaces and permit ingress of cement fines and the formation of hydrates (28) in these spaces.
