  • Testing the Explosion Resistance and Energy Absorption of

    The explosion resistance performance of two groups of high-strength reinforced concrete (RC) slabs versus common RC slabs was studied experimentally by Lu et al. as part of an exploration into the failure mechanisms and the development and distribution of cracks in concrete. The results indicate that the adoption of HHT 600 high-strength steel
