ABSTRACT
Work related to the restoration of physical, worn-out and individual elements of storage structures, in particular water tanks and water intake structures, water supply systems is the most relevant..
Key words: polymer concrete, porous material, mortar mixture
Work related to the restoration of physical, worn-out and individual elements of storage structures, in particular water tanks and water intake structures, water supply systems is the most relevant. Although structures of this type are periodically repaired with conventional building materials, the technical level of the structures being restored is much lower than the level of structures being restored using composite building materials.
The technical condition of the structure is mainly assessed on the basis of material analysis and examination of defects, damages and verification calculations. Defects and damage, excessive deformation and crack opening are established on the basis of visual and instrumental examinations.
In practice, significant parts of the reservoir structures are erected from reinforced concrete in a prefabricated, prefabricated monolithic and monolithic version. Concrete is an artificial building material, and a significant part of its volume is occupied by pores and capillaries. Structurally, concrete after hardening is a porous material. In construction practice, there are various methods that reduce the porosity of concrete: - mechanical (vibration and curing), - the use of various plasticizing additives (C-3 C-4 GKZh silicon organic liquids) in different ratios of the mass of cement. But these methods of reducing the porosity of concrete are effective when concreting structural elements of tanks or various reinforced concrete structures of buildings and structures in a factory.The preparation of a concrete and mortar mixture with the addition of various plasticizers, superplasticizers, in the conditions of a construction site, when restoring performance, does not give tangible effects (since their compaction is much more difficult, it is not in the factory).
Studies show that with the ratio P / C-02-05 (polymer / cement), polymer - cement compositions, building materials are effective in the treatment of damaged areas or
areas with defects in reinforced concrete structures. Razrschetr! polymer concretes based on furan, phenolic, epoxy resins.
Polymer concretes are beneficial, they can also be used for the restoration of pressure, without pressure pipes of various engineering awns and sewer pipes. Polymer concretes are concrete based on a high molecular weight binder, they are the most rational effective building material. When restoring the performance and durability of tank structures, such as reinforced concrete tanks for water and various reinforced concrete pipes for sewers and irrigation networks.
The elimination of the wear and tear of such structures will entail significant savings in capital executions during repair work in quality and economic terms.
