British power station built with low-carbon cement

A power station in Wales was built using low-carbon Phoenix Portland fly-ash cement to reduce its carbon footprint. The fly ash was produced locally, at a sister power plant. CelticAsh and Lafarge Tarmac worked with RWE npower to ensure that the product was a low carbon cement that still met the structural requirements of the project. "The ash content of the cement [typically around 30%] significantly reduces its heat of hydration, which in turn reduces the risk of thermal cracking in large concrete pours," said Allan Everett, general manager of CelticAsh.
