  • Self-compacting concrete (SCC) is a new type of concrete which can easily flow and consolidate without any compaction due to the present of high content of water reducing while keeping a low water-cement ratio. There are many advantages using SCC during construction practice; for instance reducing cost and maintaining the good working environment. Therefore, use of SCC has been increased since it was introduced in 1980’s. However, segregation and settlement have to be concerned in such congested section or complicated reinforcement like in beam-column structural elements. The uniformity of the properties of SCC in this element was investigated using non-destructive testing (NDT)-hammer testin some considering point of elements in this research. The specimens are full-scale of beam-column structural elements. It consists of three specimens made from SCC and three specimens made from conventional concrete as comparison (NC). To confirm the result of hammer test, the specimens were then loaded until failure. According the hammer test, there is only slight differences in rebound number between NC and those of SCC indicatingthere is a uniformity of structural elements. However, during structural testing, in higher reinforcement ratio, the SCC aren’t able to reach the maximum load as NC due to early failure occurred in column indicating there was a problem during placement which cannot be detected during NDT. More than one NDT tool has to be utilized to evaluate the uniformity of structural elements.
