Abstract

This research goal is the adding of pozzolana as rough aggregate in concrete. Pozzolans of Jabl Onyzh have been described as the major supply from Jordan. It is often used in the place of a conservative aggregate in frivolous concrete. A practical examination was carried out on the resistance of Pozzolana Lightweight Concrete (PLWC) with diverse ratios (35 and 50%) of pozzolana from the whole size of admixture order to ascertain its impact. In this study, a design mix was used with several A mix design was determined through various experimental mixtures to make certain that the pozzolanas lightweight concrete will be able to attain the needed fundamental performance. A self-fabricated was used to simulate a low-velocity projectile effect on the slab specimens was aroused with the use of a self-invented drop-weight impact test rig. Twofold factors were examined to determine the impact resistance on slab (300×300 mm) with diverse viscosity (20, 25 and 30 mm) support, with pozzolana content and concrete thickness. The impact resistance of concrete decreases with the addition of pozzolana but progresses with slab thickness. However, the influence is more prominent for the final crack resistance than for the first crack resistance. When slab thicknesses were compared with each other, the outcome was that 25 cm has a general superior performance in lightweight concrete for impact resistance.
