... locations within the member (i.e. top, middle and bottom regions) and investigated using a multi-level assessment protocol through microscopic (i.e. damage rating index) and mechanical (i.e. stiffness damage test) test procedures. Cracking travelling parallel to the coring direction in the extracted cores...

... and cracking orientations. Diagnostic tools such as the stiffness damage test and damage rating index provided insights into internal microcracking and reduction of the modulus of elasticity, accounting for the influence of environmental exposure conditions. Measurements of strain and residual tensile strength...
