Production of building materials is mostly energy consuming. In the sphere of insulation materials we mostly see rock wool based materials or foam-plastic materials whose production process is demanding from material aspect and raw materials aspect as well. At present the demand for thermal insulation materials has been growing globally. The thermal insulation materials form integral part of all constructions in civil engineering. The materials mainly fulfill the thermal insulating functions and also the sound-insulating one. The majority of thermal insulation materials are able to fulfill both of the functions simultaneously. The paper describes questions of thermal insulation materials development with good sound properties based on natural fibres that represent a quickly renewable source of raw materials coming from agriculture. The main advantage of the materials are mainly the local availability and simple renewability of the raw materials. In addition an easy recycling of the materials after their service life end in the building construction and last but not least also the connection of human friendly properties of organic materials with advanced product manufacture qualities of modern insulation materials.

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].

This paper presents the results of studies on mineral powders dispersion degree effect on the properties of alkaline cement-water paste where powders are of natural and technogenic origin. The change dependences between the total specific surface area and the duration of grinding have been studied, and the optimal grinding time for raw materials has been revealed. The developed formulations of cementing alkaline binders, with the use of mineral powders and wastes from the cement industry, are distinguished by short setting times and high consumption of alkaline grout to obtain a cement paste of normal density, which requires further research. And the obtained influence patterns of the degree of dispersion on the properties of the "mineral powder - Na2SiO3" binder will make it possible to create strong and durable artificial building composites competing with concretes based on Portland cement.

Environmentally Safe

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.

The paper investigates the surface wet magnetic separation (WMS) technogenic raw materials concentration tailings particles properties. The mechanical activation effect nature on the binder structural and phase characteristics is revealed. High pozzolan activity of WMC tails, which consists in genetic and morphological features of the surface of poly-mineral structures has been established. During mechanical activation of lime together with WMS tailings, an increase in the number of neoplasms occurs in the amorphous phase form with a low degree of polymerization, which is confirmed by the acid-soluble SiO2presence, as well as by X-ray phase analysis. The work results indicate a WMC waste particles surface high energy potential for its use in building materials for autoclaved hardening. This study will contribute to the energy and resource-saving technologies development, the solution of environmental problems in order to create a comfortable environment for life and work.

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.
