Abstract. The article deals with the production technology of prefabricated structures using fiber cement. Studying the properties of these structures, the author points out that the use of fiber cement made of polymer fibers is advisable in the manufacturing process of prefabricated structures, as a result of their use increases crack resistance, impact strength, fracture toughness, wear resistance, frost resistance, cavitation resistance, and also decreases shrinkage and creep Also in the article noted that the use of fiber cement structures without reinforcement is possible, if their primary work is aimed at compression in the case of the location of the longitudinal compressive force within the cross-section of the element or if the longitudinal compressive force is located outside the cross-section of the element and the bend, but it should be borne in mind that their destruction should not create an immediate danger to such objects, the life and health of workers, it is also necessary to control the serviceability and safety of the equipment.

The author comes to the conclusion that today there are a number of opportunities to create high-strength fibroblasts of new generation, using domestic raw materials. Modern effective types of fiber make it possible to simplify the process of its introduction and mixing in the concrete mix, as well as make it possible to use technological equipment that is used in the manufacture of conventional concrete. At the same time, it is possible to obtain and use fiber cement mixtures with high mobility.
