Abstract

Capitalization of tires waste is a priority problem determinate by the large quantities of these waste and environmental impact generated. In this paper we recommended capitalization with obtaining of new material with improved proprieties. The durability of a new polymer concrete with tires waste powder is presented in this paper. Durability characteristics such as: water adsorption, the chemical resistance, frost thaw cycles resistance, and thermal shock strength were performed. Influence of resin content and filler content were analysed. Thermo-physical tests have shown a very good behaviour of epoxy concrete with tires powder subjected to different types of aggressive agents, compared with that of witness polymer concrete, without addition. Results show that polymer concrete with tire powder display a very good behaviour to: frost-thaw cycles, thermal shock and chemical attack. The use of tires wastes in polymer concrete may help to improve the environment by elimination of a pollutant and to obtain a new composite material for construction industry. This new composite which uses powder of waste tires is a lightweight concrete, with good durability properties, which can successfully replace the cement concrete in specific applications such as: prefabricated unit for sound protection, thermal insulation, floors for chemical industry, pavements, etc.
