“…An urgent problem of use of BPA in construction is confirmation and justification of retention of properties at a high level during long-term operation in a variety of climatic conditions. However, in all the works listed [1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16], there is no information about a change of properties of BPA for construction purposes under the action of natural climatic conditions of different zones. In [17], the strength of basalt, carbon and glass fibers was studied in accelerated tests simulating the natural weather conditions, but conclusions obtained were not verified by direct climatic tests.…”
