Figure Lengend Snippet: Material parameters for the large quarzitic aggregates and the calibrated parameters for mortar, containing a volume fraction φ q u a r t z = 30.34 % of fine quarzitic aggregates. The mortar matrix is assumed to contain a 8.3% volume fraction of initial microcracks with an initial aspect ratio of 23. In the investigated concrete sample, the material properties of the mortar matrix with a volume fraction of φ q u a r t z = 43.95 % are determined by varying the volume fraction of aggregate accordingly in the Mori–Tanaka based homogenisation procedure, while keeping other parameters unchanged (group Model parameters ). The following sources are used to determine the parameters: [ 1 − 3 ]—Experiment, [ 4 , 5 ] aspect ratio is taken within the range measured in [ 69 ], 6 —[ 24 , 70 ].
