We consider the process of obtaining carbon-silica fillers via pyrolysis- cum-water vapor of worn out waste tires to be a method alternative to the co-fuming process. Generally, the pyrolysis of tires is described as a tire recycling method.34 We assumed that a dual phase filler could be obtained if the tires subjected to pyrolysis were not standard ones (filled only with CB), but the so called green tires comprising a high quantity of silica. We expected carbon to be formed due to the pyrolysis itself, as a result of the destruction of elastomers. The method is attractive, mostly because an essential environmental problem might be solved. On the other hand, the dual phase filler obtained has the advantages described above.

Because of the huge generation of tires and the several environment impacts that are caused, the tire recycling has become a necessity. There is about one worn tire produced per year and per person in the developed countries (Roy et al. 1990).

The incorporation of waste-stream materials in concrete mixtures has been an important contributor to concrete production for several decades. Materials such as fly ash, which require specialized landfills if disposed, are repurposed in concrete production while providing additional benefits to concrete properties. The use of these materials in concrete has obvious benefits, and therefore, instead of discarding this waste, it is sold thereby providing an additional economic value. The use of recycled tires in concrete production can provide many of the same life-cycle benefits that more traditional supplementary concrete materials offer. The major benefits of using recycled tire aggregates in concrete are not found in the direct economics of the material, but rather in its effect on concrete properties and its life-cycle analysis. One major benefit of the use of recycled tire aggregates is the proximity of the manufacturers. Tire recycling facilities are located in and near major metropolitan areas, resulting in reduced transportation costs when compared to natural aggregates that may be trucked or railed in for use in urban concrete construction.
