Concrete is the main and popular construction material in Malaysia. Cost effectiveness and durability are the main factors that make them the best and affordable materials in Malaysia. In this paper, we present a non-destructive approach for high strength concrete with the inclusion of POFA. Apart from that, crack monitoring of high strength concrete with POFA is also monitored. High strength concrete is designed for Grade 60 and the utilization of POFA acts as an additive from 2.5, 5 and 7.5% from cement weight. All specimens will undergo water curing and testing on 7 and 28 days. All samples will be evaluated for NDT testing using rebound hammer and UPV and eventually after NDT samples will be tested for bending using an universal testing machine to see the flexural behaviour and crack pattern. From this report, it is seen that NDT testing shows a similar result as compared to the destructive test. In addition, the utilisation of POFA at every level of addition in concrete also enhanced the cracking behaviour of concrete. In conclusion, the utilisation of POFA is a proof to enhance the concrete performance in mechanical properties. Apart from that, the NDT approach can be an alternative to investigate the mechanical properties as compared to the destructive test. © 2023, The Author(s), under exclusive license to Springer Nature Singapore Pte Ltd.
