To care for hardening road concrete in the modern practice of the construction of coatings and grounds, the use of film -forming materials that provide reliable and effective in technical and economic terms Protection of freshly laid concrete is characteristic. In addition to film -forming materials, other methods of concrete protection are also used. All concrete care operations are carried out in three stages: preliminary, main and final. The preliminary stage begins after the final passage of the concrete finishing machine and lasts until the concrete coating of the film -forming fluid is applied to the surface. The purpose of the work is to protect freshly laid concrete in a short period when for technological reasons it is impossible to apply a film -forming material. The main stage begins to apply a film-forming material to the surface of the coating and is completed in a period of at least one month, when concrete acquires a design (loom) strength: the purpose of the main stage is the creation of the necessary temperature and humidity conditions for hardening concrete during this period, which is the key to the formation of the formation its structure and properties that meet the requirements of a given strength and durability. The final stage provides for the implementation of the necessary operations to clean the coating from materials used for its thermal protection, and is performed after a concrete of design strength is performed by concrete. The purpose of this stage is to prepare a concrete coating for operation. Throughout all the stages, in addition to thermo operations and the moisture protection of concrete, they provide for reliable protection of solid concrete from mechanical damage from random collisions of transport, walking people, pets.
