This paper presents CDW-soil mixture behaviors, under static load. The CDW sample was collected in a recycling site located in Maringa, Parana, Brazil. In addition to natural soil and CDW, cement (3.5%; 7.0%) and polypropylene fiber (0.25%; 0.50%) were used. The mixtures were prepared using 75/25 and 50/50 percentages of soil and CDW, respectively. Experimental results show that unconfined compressive strength (UCS) and tensile strength (TS) increase as the CDW content increases in the mixtures. The results show that UCS and TS are more influenced by cement content than fiber content. For experimental values, a multiple regression was obtained showing good agreement between experimental and theoretical values. However, this experimental study does not consider the effect of fiber length and CDW cementation, which are important parameters for strength results.
