A Brief History of the development of silica fume

1947: the city of Kristiansand in Norway Fiskaa AIKEN Group factory, the world's first collecting silica fume.
1951: the beginning of the application of concrete tests, silica fume concrete in 1952 the first time in engineering applications (BERNHARDT Oslo Tunnel).
Age 70: Production of collecting technology matures silica fume to improve the performance of concrete caused widespread interest in applied research work in full swing in the world. Norway took the lead in the promulgation of silica fume cement and concrete in a mixed application of national standards.
80 era: the rapid development of application technology, expanding the field of concrete applications, the amount of rapid growth. Norway for the first silica fume shotcrete and shotcrete is fast becoming a standard component. Pumping high-strength concrete (80 ~ 130MPa), high impact grinding the successful application of concrete in the United States.
90's: to become widely used pozzolana mixed materials, to improve fresh and hardened concrete properties. Worldwide annual capacity of more than 100,000 tons.
European and American Concrete Institute in the preparation of silica fume on the concrete application of the Guide, Norway, France, Australia, Canada, the United States, Japan, China and other countries have standards for silica fume products.
