Durability properties of concrete with recycled waste tyres

Concrete industry is one of the major consumers of natural resources. The main aim of sustainable development is to find alternative resources, which could decrease negative effect of concrete industry on environment and contribute to preservation of natural resources. Huge amounts of waste tyres accumulated all over the world are recognized as good supplement for natural resources in concrete. In this paper is given an overview on possible use of waste tyres in concrete as replacement of part of the aggregate. Research encompassed comparison between mixtures with different chemical and mineral admixtures with the main aim of achieving economically eligible, ecologically acceptable and more efficient concrete mixture. The investigation included examination of mechanical and durability properties such as: compressive strength, gas and water permeability, capillary absorption, chloride diffusion and resistance on spalling due to freezing and thawing of CRT (Concrete with Recycled waste Tyres). Results presented in the paper show that in specific applications CRT is interesting alternative to normal concrete.
