• Fibre reinforced lightweight aggregates 

      Bernhardt, Markus; Tellesbø, Hilde; Justnes, Harald; Wiik, Kjell (Journal article; Peer reviewed, 2014)
      Carbon steel fibre reinforced lightweight aggregates (LWA) were produced in a pilot scale rotary kiln. Narrow size fractions as well as not-sieved (asreceived) material were investigated according to European standards ...
    • Mechanical properties of lightweight aggregates 

      Bernhardt, Markus; Tellesbø, Hilde; Justnes, Harald; Wiik, Kjell (Journal article; Peer reviewed, 2013)
      Lightweight aggregates (LWAs) were successfully produced both in a pilot-scale rotary kiln and in a laboratory chamber furnace. The mechanical properties of LWA were investigated in detail applying the European standard ...
    • The effect of heat treatment and cooling rate on the properties of lightweight aggregates 

      Bernhardt, Markus; Tellesbø, Hilde; Justnes, Harald; Wiik, Kjell (Journal article; Peer reviewed, 2014)
      Lightweight aggregates (LWA) were produced from clay in the laboratory. After firing different heat treatments and cooling rates were applied andthe resulting material was investigated with respect to strength and ...
