It often seems nowadays that no one in the construction industry likes using Portland cement and they are always investigating ways and means of replacing it (Goodier, 2013). Its poor environmental credentials are the main reason for this, and with so many excellent variations of cement replacements currently available, the industry has no excuse for not producing and using concrete with a much lower environmental footprint than in the past. The first three papers in this issue are excellent examples of what can be done when replacing cement with some imagination, and careful consideration and thought.
