Accelerated Wear Testing of High Strength Concrete in Norway

To give guidelines for the mix design on high performance concrete with high wear resistance, and to study wear of high strength concrete, the Norwegian cement producer NORCEM operates a test rig specially developed for this purpose. The tests show concrete to give 2-3 times the wear resistance of asphalt. Compressive strength is proven to be the most important parameter for wear resistance. Other mix design parameters will also influence the wear properties of the concrete. The test rig has been improved and reestablished and the variation coefficient of the test method has been significantly reduced.
