This study analyses the outcomes from an investigation on the "Impact Resistance of Lightweight LECA Aggregate Concrete (LWLAC) with Steel Fibre". The utilization of Lightweight Expanded Clay Aggregate (LECA) as a substitute for normal aggregate in lightweight concrete can encourages its negative environmental effects. There is lack of research on the impact resistance and crack behaviour of concrete; exceptionally in LWLAC reinforced by steel fibre. Through the use of a self-fabricated drop-weight impact test rig, the replication of a low-velocity projectile result on LWLAC slab 300 mm x 300 mm size with 20, 30, 40, and 50 mm thickness was reached by dropping two kinds of steel ball (weighing 0.509 kg and 1.05 kg), with completely different of drop stature.
