Abstract [en]

The study addresses several aspects of Rock-Filled Concrete (RFC) – a new construction material developed for use in hydraulic structures. Some of the latest results of compressive strength, tensile strength and compaction level of the material are presented. In RFC, Self-Compacting Concrete (SCC) is used together with large aggregates (minimum of 30 cm in size), to produce concrete with a high content of aggregate material and a low content of cement. The large aggregates in RFC complicate the material testing. In this study, the aggregate size is limited to 150 mm in size and the strength parameters have been evaluated using cubic samples with a surface area of 500 * 500 mm. The results imply that RFC does not lead to reduced material strength as compared to SCC. Based on the latest performance results of the material, together with results from earlier studies of the production costs and environmental impacts of RFC, the conclusion is that RFC has advantages of lower material cost, faster construction and less environmental impacts as compared to both conventional concrete (CC) and Roller-Compacted Concrete (RCC) when used in large concrete structures such as dams.
