  • Studies of dustiness in a residential area located near industrial enterprises with PM10 and PM2.5 particles

    Air pollution in residential areas near industrial plants is one of the most significant problems of modern ecology. The resulting dust is one of the important factors in assessing the adverse impact on the environment. Studies show that the greatest danger to the human body is particles up to 10 microns in size. When analyzing the dispersion of dust in the residential and industrial areas, it is possible to estimate the percentage of particles PM10 and PM2.5 from the total amount that is necessary to effectively control the effects of dust on human health. The article gives a comparative analysis of the results of studies of the dispersion composition and dust concentration in the air of the working zone and the urban environment.

  • The production of cellular concrete using local materials

    The paper proposes a new foam based on cement and the steelmaking slag, which is obtained and developed at the Department of construction materials and special technologies, IAIS VSTU. The purpose of the survey was to obtain an effective insulating material for wall building envelopes, in high-rise housing construction and of the material for use in low-rise construction in the manufacture, which would maximize the use of local raw and production resources. When selecting components, special attention was paid to the resource base of existing enterprises of Volgograd, analyse the products of local manufacturers. The tests were conducted in the laboratory and on the production line. It is known that the slag used in the production of building materials rarely, usually just transported to dumps by truck. At the plants, open hearth plants, slag with shlakovoza buckets are taken and poured as a melt into slag pits. Use water spraying for crushing slag due to thermal shock when the temperature drops.
