In a process for producing fiber-reinforced hydraulically setting extruding materials, the process which comprises, not adding the reinforcing fiber in the form of single fibers to the starting materials, but employing it as collected yarns by collecting the single fibers with a collecting agent, uniformly dispersing them in the starting materials, then releasing the collected condition of said dispersed collected yarns and splitting into single fibers by swelling and dissolution of the collecting agent and by the shear force by a screw etc., thereby the dispersion is improved. The single fibers having a great aspect ratio which have been released from the collected condtion are uniformly dispersed in the extruding material, and a remarkable reinforcing effect is obtained.
