Abstract: Increased productivity and improved working environment have had high priority in the development of concrete construction over the last decade. Development of a material not needing vibration for compaction - i.e. self-compacting concrete, SCC – has successfully met the challenge and is now increasingly being used in routine practice.
The key to the improvement of fresh concrete performance has been nanoscale tailoring of molecules for surface active admixtures, as well as improved understanding of particle packing and of the role of mineral surfaces in cementitious matrixes. Fundamental studies of rheological behaviour of cementitious particle suspensions were
soon expanded to extensive innovation programs incorporating applied research, site experiments, instrumented full scale applications, supporting technology, standards and guides, information efforts as well as training programs.
The major impact of the introduction of self-compacting concrete is connected to the production process. The choice and handling of constituents are modified as well as mix design, batching, mixing and transporting. The productivity is drastically improved through elimination of vibration compaction and process reorganisation. The working environment is significantly enhanced through avoidance of vibration induced damages, reduced noise and improved safety. Additionally, the technology is improving performance in terms of hardened material properties like surface quality, strength and durability.
