Abstract: In 1998, 24 Dutch precast concrete element manufacturers united in the association BELTON initiated the project to investigate the possibilities to apply Self Compacting Concrete in the industry. The required knowledge on SCC showed to be not available in the Netherlands, so it was decided to ask Kajima Corporation in Tokyo to transmit their knowledge on SCC to a small group of BELTON representatives. That was effectuated in the fall of 1998 at Kajima Technical Research Institute, KATRI, in Tokyo. The gained knowledge was then spread to all manufacturers and a huge collective development project of 24 companies started. Within 1 year the first commercial production was a fact and in 2000 most of them were producing SCC on a daily base. After having followed training courses organized by BELTON nowadays over 60 Dutch precast companies apply daily SCC for precast products of all kind under third body control; in 2004 almost 800.000 m3.
SCC differs in many aspects from vibrated concrete. Attention has to be paid to:
the mix design procedure, the characteristics of fresh SCC in relation with the product, the modifications in installation and equipment, the mould technique, the way of casting and finishing, the appearance, the mechanical properties, the durability and the economical aspects. The listed aspects are discussed in this paper.
