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.
