Fiber-reinforced concrete can be made using regular mixed concrete or in mortar, as long as the fibers mix in evenly throughout. Things to consider when mixing fiber-reinforced concrete are the water to cement ratio, and the size of the fiber (referred to as the aspect ratio, which is the length of the fiber divided by the diameter).
