The article presents the results of research an effect of glass-plastic fiber on the properties of heavy concrete. It determined that adding glass-plastic fibers in heavy concrete compositions in an amount of 0.5 to 2.5 % by volume leads to decreasing of slump from 20 to 5 cm, increasing air entrainment on 0.3 ... 0.6 % and reduction in density to about 50 kg/m3. Found dependence of the strength properties of concrete classes B20, B30 and B40 depending on the content of glass-plastic fibers. Introduction of fibers into concretes of different classes in an amount up to 2.0 % by volume leads to an increase in the compressive strength on 7 ... 10 %, tensile strength at bending – up to 14...36%. Defined the perspectives of the use of glass-plastic fiber and ways to improve efficiency in the heavy concrete.
