Green technology and sustainable development are the main concern in any country around the
world; researchers and engineers are urged to provide the best solution to maintain the
environment for the future generation. Malaysia is the world largest oil palm exporter, producing
over 4 million tons of oil palm shells as main solid waste of the industry annually, which causing
an environmental problem. An optimum mix design should be acquired through various trial
mixes to ensure the re-use of oil palm shells lightweight concrete to achieve the required
structural performance. A self-fabricated drop-weight impact test rig, have been used in this
research work, to simulate a low-velocity projectile impact on the slab specimens. Three
parameters are tested for specimens with or without geogrid reinforcement; where the first
parameter is the effect of OPS content on impact resistance, and it is found out that the increment
of OPS content will reduce the impact resistance of concrete. For the second parameter, the
effect of geogrid layers on impact resistance is evaluated; as the increment of geogrid layer does
improve the impact resistance, but the effect is more obvious for ultimate crack resistance than
the first crack resistance. The last parameter is the contribution of geogrid type on impact
resistance; comparison are made between geogrid 60/60 and geogrid 80/80, result show that
geogrid 80/80 has the overall better performance.
