My concrete mix design is as follow,

- Cement: 370 kg CEM I (local production)
- Micro silica: 30 kg (local production)
- Water: 155 kg

Coarse aggregate: 590 kg + 490 kg, crushed limestone.

i can not find the silica fume percentage in the database, how can i use that to achieve reduction below the baseline considering that my licsence is expert. i have tried to make a private data but it is required an EPD
