Abstract

Rational decision problems of ecological safety of construction and municipal services is directly related to the simultaneous implementation of environmental requirements and the program “Housing”. For this purpose, in an article for the environmentally sound disposal of technological waste and the technology of production of concrete products. The article deals with the disposal of such waste by using an integrated approach. It includes the prevention and/or reduction of waste, minimize their negative impacts on the environment, their use with involvement in economic turnover as a source of raw materials for production of building materials, particularly environmentally friendly aerated concrete products with the regulatory technical properties. The paper evaluated the use of man-made waste and organic-mineral modifier derived from them, from the standpoint of environmental safety. A two-stage method of waste disposal under the scheme: a) providing a complex organic-mineral modifier; b) providing a non-autoclaved aerated concrete hardening with the specified modifier and the “depth” of phosphogypsum waste.

Keywords

environmental safety, recycling of technological waste, ecological assessment of technological waste and organic-mineral modifier.
