Отмечается актуальность разработки и внедрение инновационных наукоемких, энерго-ресурсосберегающих, экологически чистых, высоких технологий из минерального и техногенного сырья в различных отраслях промышленности. При этом важная роль в использовании сырьевых ресурсов в строительной отрасли принадлежит промышленности строительных материалов, особенно использованию природного сырья и в этой связи разработке инновационных проектов, позволяющих осуществлять освоение месторождений нерудного сырья, в том числе вскрышных пород, включая добычи, переработку и производство строительных материалов. Практикой установлено, что производство строительных материалов из техногенного сырья обходиться намного дешевле, чем использование природного нерудного сырья, поскольку некоторые отходы производства можно применять без соответствующей обработки, то есть исключаются технологические операции добычи, обработки, транспортировки, хранения, контроля, являющиеся частью общего производственного процесса. Приводятся результаты теоретических и экспериментальных исследований проведённых в Институте Геологии ДНЦ РАН с целью применения глинистых сланцев, аргиллитовых глин, кремнеземистого и техногенного сырья для изготовления вяжущих веществ, теплоизоляционных и стеновых материалов нового поколения, получаемых по инновационной, наукоемкой, низкообжиговой и безобжиговой, следовательно, энерго-ресурсосберегающей технологии. The relevance of the development and implementation of innovative high-tech, energy-resource-saving, environmentally friendly, high technologies from mineral and industrial raw materials in various industries is noted. At the same time, an important role in the use of raw materials in the construction industry belongs to the building materials industry, especially the use of natural raw materials and, in this regard, the development of innovative projects that allow the integrated development of nonmetallic deposits, including overburden, including mining, processing and production of building materials. It has been established by practice that the production of building materials from technogenic raw materials is much cheaper than using natural non-metallic raw materials, since some production wastes can be used without proper processing, that is, technological operations of extraction, processing, transportation, storage, and control, which are part of the overall production process, are excluded. The results of theoretical and experimental studies carried out at the Institute of Geology of the Dagestan Scientific Center of the Russian Academy of Sciences with the aim of using shale, argilite clay, silica and technogenic raw materials for the manufacture of binders, heat-insulating and wall materials of the new generation, are obtained from innovative, high-tech, low-firing and unburned, therefore, energy resource-saving technology

Вопросы ресурсосбережения являются приоритетными в промышленности строительных материалов и изделий, все большее распространение получает применение техногенного сырья в строительных композитах. Это диктуется необходимостью утилизации техногенных отходов, повышением экономической эффективности производств и вопросами защиты окружающей среды. Особый интерес в проектировании составов строительных растворов представляет применение местных некондиционных песков, техногенных песков из отсевов бетонного лома и кирпичного лома. Данная статья посвящена исследованию зернового состава отсевов дробления бетонного лома и кирпичного боя, возможности создания рецептур строительных растворов на мелких песках с их использованием. Для большинства регионов нехватка крупнозернистых песков является особо актуальной, так как без их наличия производство бетонов и растворов высокого качества проблематично. Одним из способов решения данного вопроса является применение отсевов и мелких фракций дробления вторичного сырья, пригодного для использования в качестве заполнителя по химико-минералогическому и гранулометрическому составу. В результате рециклинга вторичного сырья образующие мелкие фракции отсевов представляют большой интерес для применения в качестве крупнозернистых песков или обогащающего материала для мелких песков с низким модулем крупности. Resource-saving issues are a priority in the building materials and products industry; the use of technogenic raw materials in building composites is becoming more widespread. This is dictated by the need to utilize industrial wastes, increase the economic efficiency of production and protect the environment. Of particular interest in the design of mortar compositions is the use of local substandard sand, industrial sand from screenings of concrete scrap and brick scrap. This article is devoted to the study of the grain composition of screenings for crushing concrete scrap and brick fighting, the possibility of creating mortar formulations on fine sand with their use. For most regions, the shortage of coarse-grained sand is especially urgent, since without their presence the production of concrete and high-quality mortars is problematic. One of the ways to solve this issue is the use of screenings and small fractions of crushing secondary raw materials suitable for use as a filler in chemical-mineralogical and particle size distribution. As a result of recycling of secondary raw materials, the fine screening fractions are of great interest for use as coarse-grained sands or an enrichment material for fine sands with a low modulus of fineness.

during the implementation of the program to restore the housing stock of the Chechen Republic, as well as during the planned demolition of dilapidated housing, significant volumes of technogenic raw materials were generated, in particular, large volumes of brick and concrete scrap. Enterprises for the production of building materials and products also produce significant volumes of production defects, which accumulate over the years at landfills. Ceramic broken brick and broken brick dropouts are used to fill the roadbed, and the main part still goes to the dump and landfill, which is also an environmental problem. One of the promising ways to use dropouts and broken brick itself is to use them as secondary aggregates in concrete and mortars. This article discusses the issues of improving the quality of ceramic concrete mixtures, choosing the optimal composition and technology for mixing concrete mixtures using dust fractions of dropouts for crushing ceramic brick bricks

The modern building materials market places high demands on heat-insulating and heat-insulating structural materials. In this connection, the issues of developing high-quality building materials obtained on the resource-saving technologies basis allowing to solve two interrelated problems are topical. The first problem is the industrial waste generated and existing stocks disposal. The second is associated with a decrease in the traditional raw materials deficit [1]. These problems solution, combining rational technological solutions, is based on the scientific research achievements in this area, in particular in the foam glass production. The priority scientific research areas in the foam glass materials production are the developments related to the study, the new raw materials use and the production of foam glass mixture compositions on their basis, which provide, along with the necessary performance properties, high environmental safety requirements [2, 3].

Abstract Today, the waste of the mining industry is more than 8 billion tons. Analysis of the literature data showed that most of the man-made waste that is generated as a result of the development of mineral deposits is suitable for use in many industries, in particular, in the production of building materials. The use of technogenic raw materials allows us to solve the following tasks: Environmental aspect - reducing the number of dumps and reducing their volumes. And this, in turn, improves the ecology of regions and territories. 2. Economic aspect - reducing the cost of construction products through the use of almost free raw materials, the release of more competitive products. Of course, it is necessary to provide that part of the costs will be spent on additional processing, revision, activation, modification of this technogenic raw material component. But today we have to think about how to clear the territory of substandard “waste rock” and use it to reduce the production and consumption of natural raw materials. A similar process can create waste-free production.

The purpose of the research is to investigate the ability to heat the parthenogenesis of new breeds silkworm T–1, T–2, D–1 silkworm breeds and to establish the reproductive, biological and technological parameters of the T–1clone, T–2clone and D–1clone created on their basis. Materials and methods of research. The research was conducted on the basis of the laboratory of silkworm and technical entomology of the National Scientific Center "Institute of Experimental and Clinical Veterinary Medicine" during 2016–2018. For the study of the ability of new breeds of silkworm D–1, T–1, T–2 to the thermal parthenogenesis, the females of the aforementioned silkworms were used. Activation of the gravel to ameiotic parthenogenesis (complete thermal pathogenesis) was carried out using the method B. L. Astaurov The reproductive parameters of parthenoclon were studied: the ability to parthenogenesis (%), the total number of eggs (pieces), the weight of one egg (mg), the output of caterpillars from eggs (%). The economic-valuable and technological indicators of the created clones were investigated: viability of caterpillars (%), cocoon yields of 1 g of caterpillars (kg), silkworm cocoons (%), cocoon mass (g), length of filaments (m), length of continuous- unwound thread (m), raw silk output (%). The main results obtained. It is established that the new clones of silkworm silk created by the ability to parthenogenesis are at the control level. In terms of the viability of caterpillars in 2018, they are somewhat inferior to Ukr.28, but according to the results of three years of research, this indicator is at a level, and T–2clone even exceeds control by 4.84% (p < 0,05). Similar results are obtained on the basis of the weight of the cocoon. By the cocoon yield, the new Parthenoclon exceeds control in 2018 by an average of 0.44 kg and for three years of research – by 0.50 kg. The indicator of silk worminess of cocoons in T–1clones and D–1clones was at the level of the indicator Ukr.28clones, at T–2clone – was higher than the parameters of part-clones and control at 0.83–2.73%. The length of the thread, the length of the continuously unwound yarn and the output of raw silk is dominated by T–2clone – its values exceed the similar indicators of T–1clone and D–1clone, dominated by control indicators – Ukr.28clones. Thus, the new clones of silkworm, adapted to the changed climate in Ukraine, were introduced and evaluated. They can be components for the creation of new clone-breed hybrids with high biological and technological performance. The stands of silkworm hybrids will provide domestic branches of production of organic raw materials for the production of modern products. This will allow import substitution of organic goods for everyday use to our country's inhabitants. Domestic production of organic products in the form of clothing, medical and cosmetic products will provide the work of thousands of compatriots and reduce the cost of goods in comparison with imported ones. Prospects for further scientific research are the creation of new clone-breed hybrids with high biological and technological indices for Ukraine. Conclusions. 1. Three new high-yield silkworm clones with the optimal combination of silk productivity and ability to ameiotic parthenogenesis, characterized by the following biological indices, are derived: T–1clone – caterpillar livelihood 84.13%, cocoon yield 3.76 kg, cocoon mass 2.30 g, silkiness 21.62%; T–2clone – caterpillars' survivability 88.94%, cocoon yield 4.23 kg, cocoon mass 2.53 g, silicone 24.25%; D–1clone. – The viability of the caterpillars is 85.52%, the cocoons are 4.08 kg, the cocoon mass is 2.41 g, and the silicone content is 21.62%. The estimation of reproductive indices of created T–1clone, T–2clone and D–1clone clones was made and their ability to heat parthenogenesis was determined. The highest ability to ameiotic parthenogenesis has D–1clone – 72.73%. Parthenoclones T–1clone, T–2clone and D–1clone for reproductive characteristics are at the level of the control clone Ukr.28clones and are promising for clone- breed hybridization. The technological parameters of the new clones are established: the T–2clone is the leader in the length of the filament (1432m), the length of the continuous unwound yarn (734 m) and the output of raw silk (46.3%) – its parameters exceed the similar indicators in T–1clone and D–1clone at 2.5% and prevail over control indicators – Ukr.28clones – by 5.5%.

Mineral raw natural resources are not unlimited. Preservation of such non-renewable resources is the most urgent task of mankind. The development of non-waste technologies, the integrated use of secondary raw materials, which simultaneously reduces environmental damage - one of the ways to solve environmental problems. Utilization of wastes makes it possible to solve issues of environmental protection as well as resource saving. In the light of environmental requirements, building materials based on recycled materials, including cellulose-containing solid waste, have significant advantages over other traditional materials. Development of technology for obtaining new effective environmentally safe composite highly filled materials based on cellulose-containing solid household waste for the production of construction products is a rational link in solving the general problem of improving the environmental situation. In the article there are three main ways of combining gypsum binder with cellulose-containing solid household waste. Investigations were carried out on the effect of changing the ratio of cardboard / gypsum binder, specific pressing pressure, sequence of combination of components on the properties of the final product. The strength of the material was determined from the values of the flexural strength, the compression to complete destruction of the sample, and at 10% deformation. Studies have been carried out to increase moisture resistance. The results showed that the most optimal way of combining is the 2 way. The increase in moisture resistance is significantly enhanced by the action of organosilicon hydrophobisers.
