Mechanical behavior of reinforced concrete with waste-tire particles under an indirect tensile test Article uri icon

abstract

  • The incorporation of triturated tire particles as an aggregate in the concrete mixture is one of the ways to take advantage of this Waste Rubber (WR) in order to improve concrete properties, such as mechanical behavior. In this research we evaluated mechanical behavior of concrete specimens prepared with different amounts WR, which partially substituted the fine aggregate, under an indirect tensile test. In contrast with other%27s researcher%27s findings, our results show that the specimens with 5%25 WR present the highest value of indirect tensile strength (TP) of 4.36 MPa. Polynomial relationships between TP and compression strength (f%27c), where Tp ranges from 0.1f%27c to 0.2f%27c. Specimens with the 0, 5 and 10%25 WR content show two types of failure: normal tension and tiple-cleft failure, described in the norm ASTM 1144-89. Nevertheless, specimens with 15 and 20%25 WR show a new failure not described in the norm, which is thought to be occurring due to the high amount of WR used. © Materials Research Society 2019.
