Abstract

From the point of view of environmental protection, new ways are constantly being sought in order to reduce the negative consequences of waste, landfills but also the amount of minerals consumed. The construction industry is no exception. Here, too, there is a demand for environmentally friendly materials and a reduction in the ecological footprint on Earth. Building materials that modify or replace their various components with waste components contribute to the sustainability of the ecosystem and allow a new perspective on waste material as a secondary raw material. This work describes experimental research, which aims to investigate the potential use of recycled rubber granulate from waste tires fraction 0/1 and 1/3 mm in cement composites as a 100 % replacement of natural aggregates and the possibility of implementing recycled rubber fraction 0/1 mm in gypsum composites. The introductory part describes the issue of waste tires and the technology of their processing, legislative regulations aimed at the management of waste tires in Europe and in the world and the course of their recycling. Another separate chapter focuses on the methodologies used in measuring the physical and mechanical properties. The experimental part of the work is divided into two stages. The first stage is devoted to the implementation of rubber granulate in combination with a cement binder and the evaluation of the results of individual research measurements. The second stage is devoted to the implementation of rubber granulate in combination with a gypsum binder and the subsequent evaluation of the results of individual measurements of the second research stage. The dissertation presents the results, which are fundamentally different from the comparative samples and their use in construction, but at the same time it opens up new possibilities for the use as a building material.
