DEVICE FOR RESTORATION OF CARRYING CAPACITY reinforced concrete building structures

摘要

The invention relates to construction, namely reconstruction - restoration of the bearing capacity of reinforced concrete structures. The object of the utility model is to restore the bearing capacity of the concrete structure, as well as the repair volume imparting additional properties of higher water resistance, resistance to aggressive environments and durability. Summary of the utility model is that the concrete building structure, comprising a volume of concrete, steel reinforcement and repair volume, in contrast to the known, repair volume made of bystroskhvatyvayuschgosya one-component composition based on cement "Ksaypeks" comprising Portland cement, very fine silica sand and activating special chemical additives, for example, mark HD-25, installed via the adhesive material, e.g., acrylic latex emulsion. The use of the device is reduced load bearing capacity of the concrete structure, properties and increased volume repair wear resistance, water resistance, resistance to aggressive environments and durability. Utility model are as follows. At the construction of reinforced concrete structures reveal location requiring repair - repair volume, and applied to prepare the surface layers adhesive material, such as acrylic latex emulsion TU 2294-040-13236052-99 and Ksaypeks, e.g., HD-25 brand TU 5775-063 -13236052-00. Operations carried out to restore the original shape of the building structure. As a result of deep penetration into the pores and crack concrete and chemical reactions of reactive species Ksaypeks with the concrete base of calcium ions the formation of crystalline compounds poorly soluble - hydrosilicates, and calcium hydroaluminates gidrosulfoalyuminatov filling cracks and capillary network, i.e. bridging capillary-porous concrete structure. Changes in morphology leading to boundaries of hardening repair volume, sealing surfaces, which increases the corrosion resistance and hence durability of the claimed utility model.
