Green construction has been a very important aspect in the concrete production field in the last decade. One of the most problematic waste materials is scrap tires. The use of scrap tires in civil engineering is increasing. This article investigates the effect of the strain rate on the confined concrete mechanical properties. Self consolidating (SCC) control and rubberized concrete mixtures were designed and used during the course of this study to test the properties of concrete having 0%, 10%, and 20% volume replacement of sand with shredded rubber. The compressive strength of the concrete was reduced by the use of rubber. The confined compressive strength was also reduced for the FRP tubes by the use of rubber. The confinement of both conventional and rubberized concrete resulted in an increase in both the compressive strength and ductility. The increase in the strain rate by two and three orders of magnitude resulted in an increase in the compressive strength and ductility of the confined concrete in the FRP tubes. |
