Fibroenothobetons with the use of sawing volcanic tuff were investigated. The compositions of fibropenot phobetons with the use of nylon and basalt fibers have been developed, which allow to significantly reduce shrinkage deformations and increase the strength characteristics of foam phobeton. The maximum increase in compressive strength by 38% and during bending by 110% is observed in samples of fibroenophoto concrete with a reinforcement of 0.6% by volume with basalt fibers. The combination of nylon and basalt fibers is more effective for reducing the shrinkage of foam photon concrete compared to mono-reinforced samples.
