The influence of the parameters of dispersed reinforcement on the properties of fibro-foam concrete analyzed. The experiment planning matrix was built. A series of samples of various compositions made of fibro-foam concrete were tested for compression and bending. The regression equations obtained in coded form, which are adequate to the calculated ones, based on the Fisher criterion. The analysis of the equations carried out and the response surfaces constructed from them, which showed that the highest values of the optimization parameters correspond to the design area with high µv and low l/d. It has been established that the introduction of a sufficient amount of short fibers into the foam concrete matrix leads to the strengthening of the material, which is provided not only by the reinforcing properties of the fibers, but also by their ability to positively influence the structure of aerated concrete.
