Main artificial materials of making the sample.
| Gangue material | Cement | Fly ash | Additive |
| Particle size/mm | 0–5 | 5–10 | 10–15 | 15–20 | 20–25 | Portland cement of 32.5 | Class II fly ash: the residue of 0.045 mm square hole sieve is less than 20%, and the burning vector is less than 8% | Early strength agent plaster | Continuous coefficient | 0.3 | 0.4 | 0.5 | 0.6 | 0.7 |
| Discontinuous coefficient | 10 | 20 | 30 | 40 | 50 |
| Ratio between water and cementitious material | 1.7 | 1.8 | 1.9 | 2.0 | 2.1 |
| Cementitious material/kg·m−3 | 50 | 100 | 150 | 200 | 250 |
| Conventional proportion: the proportion of water, cement, fly ash, and gangue waste is 1.3 : 1 : 1 : 9. Cast a cylindrical sample of 50 mm 100 mm |
