title = "Portland cement free steel fibre reinforced concrete for structural tunnel applications",
abstract = "Large CO2 emission of concrete primarily caused by the production of Portland cement, drive the interest in innovative construction materials with less environmental impact. Alkali-activated concrete, often referred to as Geopolymer concrete, may reduce CO2 emission by up to 80\% in comparison to OPC based concrete. Many publications on alkali-activated and geopolymer concrete lack information on structural performance. For the first time in Denmark, a Portland cement free steel fibre reinforced concrete produced with GGBS and low-kaolinitic calcined clay of Danish origin has been developed and tested. Promising structural performance has been observed in 3-point beam bending tests. The availability of the used raw materials in industry relevant quantities allows to implement the developed concrete in real structural applications.",
