Abstract
A synthetic reinforcement fibrous material comprising releasable fibrous units during concrete mixing, where the fibrous units have a main filament element and plurality of integral outward extending subunits, useful as secondary reinforcement material and having a low Young's modulus for a more uniform distribution throughout a cementitious mixture incorporating the fibrous material, and imparts good finishability, strength, improved plastic shrinkage crack control, in also provides improved conformability within cementitious forms, especially within forms comprising bends. Improved cementitious compositions and fiber-reinforced concrete building products incorporating the synthetic fibrous material are also provided, as well as methods for making these materials.
