The use of OPS as a substitute for regular aggregate in lightweight concrete will help reduce its negative environmental influence. There is a lack of research on the impact resistance and crack behaviour of concrete; specifically in OPS lightweight concrete reinforced by polypropylene (PP) fibre. The replication of a low-velocity projectile effect on slab samples was achieved by dropping two types of steel ball (weighing 0.380�kg and 1.25�kg), with drop height of 360�mm, through the utilization of a self-fabricated drop-weight impact test rig. A total of 12 cube specimens, with dimensions 100�נ100�נ100�mm, were used to prepare 36 slabs with various thicknesses. The 36 slabs were prepared using a concrete cutting machine to excise the three cube specimens from each mixture, into 20, 30 and 40�mm thicknesses. Impact resistance tests were then performed on them. The results demonstrate that there was a strong linear relation between volume fraction of PP fibre and impact resistance; as well as crack resistance ratio. This relation was indefeasible by changing the thickness from 20�mm to 30�mm and 40�mm. Although increasing the thickness improved the impact resistance significantly, the effect was more pronounced for ultimate failure crack resistance than for first crack resistance. � 2016 Elsevier Ltd Final 2023-05-29T06:11:29Z 2023-05-29T06:11:29Z 2016 Article 10.1016/j.conbuildmat.2016.07.026 2-s2.0-84978525586 https://www.scopus.com/inward/record.uri?eid=2-s2.0-84978525586&doi=10.1016%2fj.conbuildmat.2016.07.026&partnerID=40&md5=0b26986d4b4c6b9d72c441806308cacc https://irepository.uniten.edu.my/handle/123456789/22651 123 394 403 Elsevier Ltd Scopus |
