Extended Abstract:<\/strong>To popularize nanoindustrial subjects in construction, to increase consumers\u2019 confidence to nanotechnological products, the main results of Russian scientists\u2019 research are publised as the abstracts.<\/p>\n

Within the frame \u00abProduction of modified fibrous concrete mixture, aimed at improving physical and mechanical properties through the components hardening the structure of fibrous concrete at micro- and nanolevels\u00bb it was experimentally proved that complex modifying additive containing carbon nanomodifier \u00abTaunit\u00bb can be applied in production of steel fiber concrete and solution; compositions of steel fiber concrete with complex modifying additives and compositions of lightweight heat-resistant steel fiber concrete have been developed. Two Russian patents (\u2116 2361847, 2386599) for inventions have been obtained. Practical recommendations concerning application of fibrous concrete mixture with reinforcer made of fiber \u00abMiksarm\u00bb and nanoadditives have been developed; technology for production of steel fiber concrete with the use of complex modifying additives has been offered.<\/p>\n

Within the frame \u00abDevelopment and optimization of fa\u00e7ade plaster compositions with increased durability based on simple and complex binders with fine natural and artificial fillers and research of their structure\u00bb it was proved that there is potential and practicability to apply nanotechnological fillers of local origins in fa\u00e7ade plasters affecting positively on the structure and properties of the composition; compositions of fa\u00e7ade plasters based on simple and complex binders modified with nanotechnological mineral fillers with high properties which provide required resistance when operated (bond resistance, compressive strength, cold resistance) have been developed. As a result of systematic fa\u00e7ade plaster optimization the share of construction market products has been minimized \u2013 binder savings are from 5 to 15%, in some compositions natural filler was completely replaced with nanotechnological product, that lead to considerable benefits.<\/p>\n

Specialists can use publishing materials in their scientific and practical activities.<\/p>\n
