The influence of the use of recycled rubber in concrete on its selected properties

Abstract

The paper deals with the area of the use of recycled materials with regard to the potential of sustainable development of the construction industry. The need for recycling and new solutions in materials engineering is constantly growing. Potential sources of recycled raw materials also include rubber recyclate, where two mixtures with different proportions of recycled rubber are compared within the proposed experimental program. The researched mixtures reflect the need for local resources, which also reflects the needs of the circular economy. The experimental program is focused on typical mechanical properties, which are supplemented by specialized tests. Among the results of the experimental program is that with significant proportions of rubber granulate, not only the mechanical properties are affected, but also the durability is significantly affected with regard to the action of the external environment.
