In the paper the cluster cracks of cement paste that has been modified with metakaolinite was analyzed. The samples were loaded with an elevated temperature based on a thermal shock. To describe the crack structure three stereological parameters were proposed to measure (i) the cluster average area ( A ¯ ) (ii) the cluster average perimeter ( L ¯ ) and (iii) the crack average width ( I ¯ ).
