A synthetic fiber material made with multipolymer blends which have been fibrillated in oriented film form is provided that is useful as a secondary reinforcement material, which has a low Young's modulus for a more uniform distribution throughout a cementitious mixture incorporating the fiber material, and imparts good finishability, strength, and improved plastic shrinkage crack control, in addition to providing improved conformability within cementitious forms, especially within forms comprising bends equal to or greater than about 45 degrees. Improved cementitious compositions and fiber-reinforced concrete building products incorporating the synthetic fiber materials are also provided, as well as methods for making the synthetic fiber materials.
