The study sought to assess the viability of partially substituting coarse aggregate in concrete with a volume ratio of 10%. Specimens prepared according to these specifications were subjected to compressive testing under varied loading scenarios. The concrete specimens, having matured for 28 days, were tested across three distinct cross-head speeds, 1, 20, and 200 mm/min to induce varying strain rates reflective of diverse loading conditions. The ensuing stress versus strain profiles generated from these tests were examined and used to study the effects of different strain rates on key compressive properties, including ultimate stress, strain at ultimate strength, energy absorption at ultimate strength, and fracture energy. Notably, the investigation uncovered that the strain rate exerts a considerable influence on the compressive characteristics of both traditional and cable fibre-reinforced concrete. A trend was identified wherein enhancements in ultimate stress, energy absorption at ultimate strength, and fracture energy were observed associated with increasing strain rates. In contrast, the strain at ultimate strength exhibited a decline under these conditions. This pattern underscores the key role of fibre inclusion in enhancing specific mechanical properties while concurrently mitigating the propagation of cracks. The integration of a 10% fibre volume fraction enhances the dynamic compressive properties of the material, making it more adept for applications in pavement. Such findings underscore the potential of fibre-enriched concrete, particularly with the addition of communication cable waste, as a robust alternative in the construction of pavements, where dynamic load-bearing capacity is essential.enCable fibre-concreteCommunication cable wasteCompressive responsesVarying loadsArticleDOI: 10.1007/978-981-96-8301-7_15
