The influence of the presence and length of synthetic dispersed reinforcement on the kinetics of plastic strength of foam concrete mixtures in the early period of hardening was experimentally evaluated. The fiber length of dispersed reinforcement varied from 10 to 60 mm. the plastic strength of foam concrete mixtures was determined during the first 3 hours of hardening. It is shown that the presence of fiber and its length are significant for the strength properties of the researched mixtures, and hence their resistance to delamination and precipitation after pouring into molds. That in turn has a positive effect on reducing the percentage of defects and the possibility of expanding the resource base in the industrial production of foam concrete products.

Keywords: dispersed reinforcement, fiber, fiber-foam concrete, cellular concrete mixture, the formation of the structure of foam concrete mixture
