(A) Testing was performed from slack conditions, and conducted with a strain rate of 0.4 %/sec to achieve quasi-static loading conditions. (B) Locations were selected from the grip-to-grip stress-strain curve. The images were then analyzed to demonstrate the effect of mineral content on the strain fields and mechanical properties. (C) Local strain fields were calculated directly. The first principal strain is shown using a heat map. (D) The relationship between modulus and mineral content was approximately linear, with the slope representing the stiffening effect of the mineral (R: Pearson’s correlation coefficient).
