The process of urbanization of great cities, the diminishing in the number of landfills, the increasing in the population growth rate and the major utilization of disposable materials have been generating an expressive volume of waste materials for the environment. Some waste materials have been reused in the last years, as for example, the residue generated by the civil construction. However, other kind of residue materials does not have been experiencing the same situation, as for example, the rubber from tires. One alternative for the reutilization of this residue material consist in use their powder in substitution of the fine aggregate in concrete. In the present paper, some experimental results concerning the mechanical properties of low strength concrete mixed with different rates of powder are presented. Finally, the experimental research reveals that is possible to obtain an ideal rate of powder incorporation without harm the strength of concrete.
