Differences Between NSC andHSC (2)• The fracture surface in NSC is rough. Thefracture develops along the transition zonebetween the matrix and aggregates. Feweraggregate particles are broken.• The fracture surface in HSC is smooth. Thecracks move without discontinuitiesbetween the matrix and aggregates.
Mechanical Behavior• Stress-strain curve is more linear• The strain corresponding to the maximumstress increases with strength• The post-peak domain gets steeper• The ultimate deformation decreases with theincreasing strength
