Mesoscale analysis of rubber particle effect on young’s modulus and creep behaviour of crumb rubber concrete

This paper presents a mesoscale model to investigate the rubber particle effect on the mechanical properties of crumb rubber concrete (CRC). Taking Young’s modulus as an example, the short-term and long-term compressive behaviour of CRC with varying rubber percentages, shapes, and sizes were simulated. As the first step of the simulation, the Walraven equation was used to convert the 3D distribution of coarse aggregate and rubber particles in an...
