The slabs were reinforced by 0.75 mm-thick BONDEK profiled steel sheets and were tested under 4-point bending load. This paper presents a case study of low-strength truck-delivered CRC poured on large-scale composite slabs. However, mixing CRC in industrial concrete plants and pouring it on-site, has had very limited implementation in Australia. CRC is not a completely new concrete class, as it has been researched in the laboratory level for a while. Crumb Rubber Concrete (CRC) is a class of concrete that is formed by replacing conventional concrete (CC) fine aggregate by crumb rubber made from scrap tyres. However, concrete mixing in construction sites or plants can suffer from some unpredictable situations, especially when implementing a newly designed concrete mix with uncommon materials in large-scale projects. Concrete mixing in laboratory conditions has a high level of quality control enabling it to achieve the designed workability and strength by accurately controlling the material quantity, mixing sequence, and mixing time.
