Abstract [en]

Crushed rock becomes more and more common as aggregate in concrete, due to the restriction to use natural gravel. Today crushed aggregate is commonly used from the size of 8 mm and upwards. Natural gravel is still used for the finer gradings. The problem with using crushed aggregate for the finer fractions is that the material is often too flaky and elongated, especially in the 0-2 mm fraction. In order to use crushed aggregate in all fractions in concrete it is important to have more knowledge about the rock material, crushing techniques and the influence on rheology of the concrete. In this project, a method has been developed to describe the geometrical characteristics of crushed fine aggregates. The materials have been sieved into different fractions and sample for analysis have been prepared for three different fractions. The method is based on image analysis where images of the material are taken with scanning electron microscopy and optical microscopy. To geometrically characterise the material, two parameters have been measured, Fmin/Fmax and F-aspect. The results show that this method is quite robust and that there is no significant difference between the two measured parameters.
