“…Развитие малоэтажного строительства способствует поиску новых, перспективных, экономичных материалов [2][3][4][5] с повышенными эксплуатационными свойствами. Конструкции и элементы для малоэтажного строительства, изготовленные из лиственных пород древесины, не могут быть полноценной заменой конструкциям и элементом из древесины хвойных пород в силу физико-механических и технологических свойств [1,6].…”

Subject of research: the article considers a relatively new material for low-rise construction modified wood solid wood with directionally altered physical properties, the natural properties of which are improved as a result of the use of modern woodworking technologies. Purpose of research: to consider the technology of obtaining modified wood for low-rise construction with increased operational properties. Methods and objects of research: hardwood birch, wood from hard-to-feed conifers pine; the proposed technology for producing modified wood allows you to obtain a new material with indicators corresponding to hardwood, due to through impregnation of the log with a modifier an aqueous solution of carbamide. Main results of research: the technology of obtaining modified wood increases its operational properties, when drying modified wood, the moisture content of wood decreases to 8 %, the content of carbamide in wood after impregnation is up to 8-10 %, density 700-730kg/ m3, strength 100-123MPa, during the pressing process, the height of the bars of modified wood decreases to 40 %, while the transverse dimensions of the bars of modified wood remain the original.

“…При механической активации осуществляется только механическая активация, а при механогидравлической активации осуществляется одновременно как механическая активация, так гидравлическая, турбулентная и акустическая активации. В процессах синтеза структурообразования участвует полученная от активации кварцевых отходов активная тонкомолотая пыль [4][5][6].…”

Subject of research: the article considers foamconcrete on quartz cement binder, the mass introduction of quartz raw materials in construction can be considered practically achievable and economically profitable. Purpose of research: the technology of foam concrete on quartz-cement binder is proposed by introducing an ultrafine filler (nanomodifier) from activated quartz waste into the binder, reduces cement consumption by 10 % and improves its physical and mechanical properties. Methods and objects of research: the nanomodifier was obtained with mechanical and mechanohydraulic activation, the proposed filler activation technologies will improve the structure of cement stone forming foamconcrete pore-forming partitions by increasing the packing density and chemical activity of nanoscale particles in the processes of hydrate compounds phase formation. Main results of research: the proposed technology of heat-insulating foamconcrete on quartzcement binder allows you to create a pore structure with a diameter of 52 microns at a density of 500 kg/m3 foamconcrete samples and a total porosity of 6575 %, and will also increase the strength characteristics of foamconcrete to 7.713.8 % due to discrete reinforcement with quartz waste (nanomodifier) of pore-forming partitions.
