The Effect of Concrete Containing Recycled Concrete Aggregate and Crushed Clay Bricks on Slab under Dynamic Loading

Abstract:

This paper investigates a set of nonlinear numerical studies slab subjected to blast loading. A three-dimensional finite element model is developed using ABAQUS by emphasizing on using concrete with recycled concrete aggregate and crushed clay bricks (RCA and CCB) to promote the strength of slab against blast loading. Different charge weights of 0.2–0.55 kg equivalent weight of TNT at a 0.4 m standoff above the slabs were considered as variables in order to evaluate damage levels and define the relations among these variables with respect to the residual strength of slab after blast. The maximum deflection and spalling ratio of the specimens were verified with the experimental data. The results corroborate that using recycled concrete aggregate and crushed clay bricks improve the strength of slabs against blast loading. In addition, the best fraction of this type of materials has been illustrated.
