| Abstract | ||||
| Concrete is arguably the most important construction material in the world. In the last decades, it has been reported that infrastructures faced extreme static and dynamic loads which caused structural catastrophic disasters [1]. The increase usage of conventional concrete in engineering industries led to high consumption of mineral resources which caused several environmental damages related to reduction in the rocket layers [2], besides, the economical damages due to the high demand of natural resources materials which rises the cost of construction [3]. Therefore, the utilization of recycled waste rubber (steel wires) in concrete can be a sustainable solution for waste construction developments [4]. Recently, two stage concrete (TSC) (non-traditional concrete) was introduced. Placing of coarse aggregate followed by injecting the cementitious materials among the aggregate layers in the formwork are the basic steps of producing TSC. Evaluating the static and dynamic performance of TSC were the objectives of this study. Cement, aggregates, water, recycled steel wires of rubber tires were utilized in manufacturing TSC specimens. The compressive characteristic and impact resistance of TSC test specimens were evaluated. Results showed that steel wires improved the dynamic behaviour of TSC, while a slight to no effect was observed on its compressive characteristics. This study demonstrates the potential to engineer sustainable TSC mixtures. | ||||
