Extended Abstract:To popularize nanoindustrial subjects in construction, to increase consumers’ confidence to nanotechnological products, the main results of Russian scientists’ research are publised as the abstracts.
Within the frame «Production 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» it was experimentally proved that complex modifying additive containing carbon nanomodifier «Taunit» 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 (№ 2361847, 2386599) for inventions have been obtained. Practical recommendations concerning application of fibrous concrete mixture with reinforcer made of fiber «Miksarm» and nanoadditives have been developed; technology for production of steel fiber concrete with the use of complex modifying additives has been offered.
Within the frame «Development and optimization of façade plaster compositions with increased durability based on simple and complex binders with fine natural and artificial fillers and research of their structure» it was proved that there is potential and practicability to apply nanotechnological fillers of local origins in façade plasters affecting positively on the structure and properties of the composition; compositions of façade 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 façade plaster optimization the share of construction market products has been minimized – binder savings are from 5 to 15%, in some compositions natural filler was completely replaced with nanotechnological product, that lead to considerable benefits.
Specialists can use publishing materials in their scientific and practical activities.
Key words: nanotechnologies in construction, modified fibrous concrete mixture, nanolevel, facade plaster, nanotechnological fillers.
