- Synopsis
- Fly ash from coal-fired power plants and other sources has various merits as a concrete admixture in terms of the improvement of durability, workability, and so on. The use of fly ash also mitigates the environmental impact of concrete by extending its life and reducing the amount of natural resources used for its manufacture. The Ishinomaki Plant has begun manufacturing carbon-free fly ash from the combustion ash of the coal-fired boiler it uses for in-house power generation. This paper summarizes the basic experimental results for concrete that uses carbon-free fly ash.
