Among the materials with potential of recycle, the PET (polyethylene terephthalate), is widely used in different industrials sectors. However, the use of this recycled material in construction industry is insignificant. In 2011, a study conducted by Brazilian Association of PET Industry (ABIPET) revealed a growth of the level of recycling of PET in 304% between 1994 and 2011. In absolute numbers this represents about 294 kilotons. This result represents the second in recycling of PET around the world, just behind of Japan. The main application of PET recycled are performed in textile industry (39,30%) and the consumption by construction industry is so small that it was not recorded in survey. Thus, this paper aims to presents the results of an experimental research developed about the use of PET recycled replacing by volume of fine aggregate in fraction of 15%, 30% and 45%. The geometric, physical and mechanical characteristics were found, between them, the dry mass, water absorption, thermal conductivity and compressive strength. Can be conclude the content that replacing of 15% of PET achieved the best results due of the biggest compressive strength, lower of water absorption, resulting from its higher homogeneity and better wrapping of composite with PET recycled.
