Tarmac has been working with ScottishPower for many years, using f ly ash in cement to produce greener alternatives for the construction industry, which require lower energy in production. Specifying Phoenix®, an environmentally friendly material, to produce a renewable energy source was an obvious partnership. On the Whitelee wind farm project, Phoenix’s lower heat of hydration generation also provided considerable benefits, as it kept heat levels in the concrete turbine bases low during the concrete pours, reducing the risk of early-age thermal cracking. “We had the choice of using several ordinary Portland cements for this project – but Phoenix® cement stood out, for ticking both technical and environmental considerations. Most importantly, a wind farm is a sustainable development, within a sensitive habitat – so using a sustainable building product like Phoenix® was an obvious choice.” Ian Smart, managing materials engineer, Morrison Construction.
