Concrete Polymer Material for the Protection of Concrete and Reinforced Concrete Structures of Hydraulic Structures from Biological Damage

Abstract

AbstractThe issues of obtaining concrete-polymer material based on local raw materials and production wastes are considered by the authors of the article. The article analyzes the operating conditions and corrosion destruction of concrete. The proposals to expand the raw material base of local materials and use waste from the construction industry enterprises of the Novosibirsk region have been made. The compositions and properties of the materials used are given. The possibility of using chrysotile-cement waste from the production of roofing building materials as a micro-reinforcing filler for a corrosion-resistant coating of a concrete surface has been determined. A concrete-polymer material of a protective corrosion-resistant coating based on production wastes has been developed. The formulation and technological parameters of the polymer additives’ introduction, which ensure adhesion to the underlying layer and the durability of the coating under conditions of biocontamination, have been developed. The structures formed in the contact zone of chrysotile cement waste and polymer components with the introduction of latex and bitumen emulsion composition have been revealed. The article presents the optimal ratio of bitumen and latex emulsion, creating the effect of corrosion resistance and good adhesion to the hardened stone of cement binders in the underlying concrete surface composition during the fibrous waste structures processing. Optimal compositions that contribute to the increase in corrosion resistance and durability of concrete-polymer material under biocontamination conditions are presented.KeywordsConcrete polymer materialConcrete corrosionConcrete biodeteriorationExpansion of the local materials and production waste raw material baseChrysotile cement wasteChrysotile cement wasteMicro-reinforcing fillersBitumen-latex compositions
