Biological testing as an important stage of preparation of the building materials for the further use

Abstract

The level of environmental safety is determined by the methods and techniques used to implement them. One of the promising areas for determining the assessment of dehydrated waste used in the construction industry is biological testing, which include the use of environmentally hazardous substances, in the form of an extract, to determine the danger degree of the samples and their further use in different areas of construction.
 Ensuring environmental safety in general is an important component in any industry. Solving issues of industrial safety, the use of hazardous tests in technology reveals the leading idea, which is considered in the scope of presenting the research results on the preparation and use of dehydrated waste from industrial enterprises.
 It is experimentally established that liquid dehydrated wastes of galvanic production are used in the manufacture of the building materials of different complexity and subsequent use. The obtained data for construction products input and heat-treated sludge (g / dm3), masonry mortars (%) and reinforced concrete with the addition of sludge (%) is only the first stage in the construction industry. The next stage is the manufacture of more responsible products ceramic tiles with the addition of sludge (%) and asphalt with the addition of sludge (%), which requires more responsible testing i.e. under critical operating conditions.
 The results of biological testing are aimed at determining the following parameters at: Dunaliella-degree of immobilization for 5 days. (%); Elodéa canadénsis - the degree of inhibition of growth in length (% to control) at exposure (d.) and Daphnia - survival at 48 days of exposure (%).
 To determine the level of environmental safety of building materials obtained from dehydrated waste of galvanic production, it is possible to accurately provide an assessment of their biological condition.
 The issues of ecological safety, safety of the natural environment, which is an important condition for the water complex of the country, using water and water resources in the technological processes of the water treatment and use systems are considered.
