THE USE OF ADDITIVE TECHNOLOGIES IN THE PRODUCTION OF DRAINAGE SYSTEM ELEMENTS

Abstract

The main task in the construction of drainage systems for open-type sports facilities is to increase the strength and reliability of drainage grates for drainage trays while reducing the economic costs of construction. To achieve this goal, it is necessary to select a concrete composition that meets increased strength requirements and, at the same time, be economically viable. The solution to this issue is possible with the use of municipal solid waste (MSW) and technogenic - mineral formations (TMF) of the mining industry to reduce the cement used as a binder. The use of additive technologies will reduce construction time and solve environmental issues through waste disposal.

Research were carried out using standard methods and proven equipment in a certified laboratory. The achievement of the set tasks was facilitated by the use of modern methods of experiment planning.

The results of the work of the authors are: the composition of glass fiber reinforced concrete with the addition of crushed glass has been developed; the composition of concretes with the addition of TMF has been developed; the addition of crushed glass to the composition of glass fiber reinforced concrete and the addition of TMF to the composition of concrete was developed and substantiated; the use of concrete with the addition of TMF is proposed for the manufacture of drainage gratings, printed on a construction 3D printer.

Theoretical and practical significance of the work: the results of the tests carried out made it possible to carry out a comparative analysis of the composition of glass fiber reinforced concrete with the addition of crushed glass and concrete with the addition of technogenic - mineral formations.

The results obtained made it possible to determine the possible application of additive technologies in the field of manufacturing drainage grids for drainage trays of outdoor sports stadiums.
