Research on Environmental Safety of Nanomodified Building Materials
The research methodology includes two directions: 1 ecotoxicological; 2 construction materials life cycle analysis.Ecotoxicological researches suggest definition of nanocomponents specifications,tracking of spreading medium,methods for identification of nano-particles in the environment(microscopic,chromatographic,spectroscopic and diffractive).The life cycle analysis was conducted on the base of approaches from risk theory,with the use of graph theory as well,which allowed to consider maximum amount of factors during materials or constructions exploitation under different conditions.As results of the research,classification of nanomodified construction materials was introduced,risks of cytotoxic components invasion in geosphere components were analyzed,some dependences of nanocomponents toxicity from abiotic factors were studied.Under the method for assessment of environmental safety of nanomodifyied construction materials an approach allowing to consider both positive and negative effect of their utilization at the same time is proposed.At the stage of designing materials and specific building elements with the use of nanomodifying additions one should foresee both positive and possible negative consequences for the environment.The article proposes ranging environmental risks for certain constructions,materials,nanomodified additions with different areas of use in construction.Approaches to reducing negative impacts on the environment when using certain nanomodifying components are developed.
