Abstract
The production of building materials is a significant reserve for increasing productivity and solving many environmental and economic problems in the construction industry. The use of any production waste in construction, especially liquid dehydrated galvanic waste, should ensure the environmental safety of their preparation and use, which are considered in the scope of the presented research. The work involves consideration of research results, which consist in the development of a block diagram of biological testing and the obtained tabular values, due to biological testing of certain types of building materials. Based on the obtained practical results, the optimal values for construction products have been developed, which determine the condition of construction materials through the use of biotesting. As a result of approbation of several test schemes, the practical values of input and heat-treated sludge (g / dm3), masonry mortar (%) and reinforced concrete with sludge additive (%) were obtained. Dunaliella-degree of immobilization for 5 days. (%); Elodéa canadénsis - the degree of inhibition of growth in length (% to control) at exposure (ext.) And Daphnia - survival at 48 days of exposure (%). The practical scheme and optimum values of production of building materials are offered, the initial application of use of products of biological testing (ceramic tiles with the addition of slime and other products with slime waste) is substantiated.
