We conducted explosion field tests on rubber concrete slabs with steel reinforcement, including four kinds of concretes with different mix proportions of volume fractions of rubber particles (0%, 10%, 30%, and 50%, termed NC, RC10, RC30, and RC50, respectively). In addition, we compared the measured over-pressure at the center of a slab with some empirical models to verify the accuracy our model. Field testing results showed that the tensile zone damage of rubber concrete slabs is smaller than that of normal concrete slabs under large explosive charges. Additionally, we validated a numerical simulation employing Multi-Material ALE and Lagrangian algorithms using the data from field experiments and employed it to further study the deformation process during the field test. Finally, we showed that rubber concrete slabs with steel reinforcements are practical structures for blast resistance, especially when subjected to a large energy detonation. (C) 2018 Elsevier Ltd.
