Figure 2. Data for powder: liquid ratio = 1. (A) Load-displacement curves for specimens with 0%, 5%, and 15% chitosan lactate. (B-E) Strength, strain-at-peak-load, work-of-fracture, and elastic modulus. Note that in (C) the strain was increased dramatically, from a mean strain of 0.2% for CPC control without chitosan lactate to a mean strain of 15.8% for specimens with 15% chitosan lactate.
