  1. Dynamic BLS Slab Experiment Test Matrix Dynamic BLS Slab Experiments • DM – Double Mat Reinforced • RS – Conventional Steel Rebar (Grade 60) • RC – Conventional Concrete (4 ksi) • HS – Vanadium Steel Rebar (83 ksi) • HC – High Strength Concrete (15.5 ksi)

  2. Dynamic Blast Load Experiment Slab #3 HC/HS/DM Pavg = 57.23 psi Iavg = 1129 psi-msec DL = 6.0 in DA = 5.5 in Figure 3. HC/HS/DM Slab#3 DBLS test video

  3. Dynamic Blast Load Experiment Slab #10 RC/RS/DM Pavg = 44.81 psi Iavg= 825.38 psi-msec DL = 4.0 in DA= 4.1 in Figure 10. RC/RS/DM Slab#10 DBLS test video

  4. Dynamic Blast Load Experiment • The slabs reinforced with vanadium micro-alloyed rebar and high strength concrete resulted in 20% less deflection and 25% less rotation than slabs reinforced with Grade 60 rebar and high strength when loaded with similar pressures and impulses. • A reduction of 45% less deflection and 84% less support rotation was observed in the vanadium micro-alloyed rebar and conventional concrete reinforced slabs, in comparison to the Grade 60 rebar and conventional concrete reinforced slabs. • The increased protection provided by using vanadium micro-alloyed rebar was witnessed in the dynamic blast load tests. The type of concrete used in construction will determine the level of protection provided. High strength concrete with vanadium micro-alloyed rebar provided the best results in terms of the least amount of damage and survival of the greatest loading in this test series.
