FIELD: construction.
SUBSTANCE: method of manufacturing of cement panels with pressed in fibers, making use of the following expression: for determination of square area of the part of the area of projected surface of fibers in the ready panel, whereat the method presupposes: securing required capacity factor of fibers of the cement mortar Vf; securing thickness of the layer of cement mortar ts,l within the range from1.27 mm - 5.08 mm; adjustment of, at least, one diametre of fiber df and thickness of the layer of cement mortar ts,l so that, rate of the area of fibers surface makes less than 0.65; securing feeding of expanded, separate fibers, presented by Vf fiber capacity factor, calculated from the above computed rate of fibers area SP f,l; securing moving cloth; application of cement mortar on to the cloth; application of the fed, expanded, separate fibers on to cement mortar; and pressing expanded, separate fibers into cement mortar so that fibers are distributed evenly along the cement mortar.
EFFECT: enhanced strength of panels.
