Table 4 The trends of change in fracture energy of concrete under varying pore diameters and porosities.
From: Concrete double-K fracture toughness and fracture energy influenced by porosity and pore size
Porosity/% | Fracture energy GF/(N/m) | ||||
|---|---|---|---|---|---|
Pore size 0.3–0.6 mm | Pore size 1–2 mm | Pore size 3–5 mm | Pore size 6–8 mm | Pore size 8–10 mm | |
0 | 215.25 | 215.25 | 215.25 | 215.25 | 215.25 |
1 | 202.35 | 202.56 | 188.57 | 205 | 205.88 |
4 | 187.67 | 196.21 | 181.02 | 196.31 | 198.09 |
7 | 179.24 | 173.28 | 170.7 | 182.41 | 181.1 |
