The improper disposal of waste tires (NFU) represents a risk to health and the environment around the world. Large-scale concrete production with the incorporation of NFU particles is a viable alternative. This study examined in detail the influence of recycled rubber particles as received (CR) and pre-treated with sodium hydroxide solution (CRT) as a partial replacement for fine aggregate by weight (5%, 10% and 15%). on the slump properties, unit weight and temperature of the concrete mix in a fresh state. Control pavers were made, with mixtures of CR and CRT for the mechanical compression and bending tests. The results of the concrete in fresh condition with CR and CRT demonstrated that the mix can maintain its workability up to 15% of partial replacement. The settlement behavior and unit weight show a linear trend with increasing rubber content. It was observed that the pretreatment method caused a nonsignificant variation up to 15% of replacement on the mixtures with CR and with respect to the control mixture. The temperature of the mixture with CR and CRT depended mainly on the pouring time and the ambient temperature. The mechanical compression and bending test also registered a linear trend to higher CR and CRT content with respect to the control pavers. The results of the CRT pavers showed a slight improvement over the CR pavers. However, the pretreatment method did not improve the mechanical properties of the pavers with respect to the control sample. In general, it was determined that pavers with CR and CRT up to 10% meet the compressive strength required by NTP 339.661 for TYPE II serviceability.
