This work shows the performances of hemp concrete in its fresh and hardened state.
- •
This hemp concrete is designed for the production of non-bearing blocks.
- •
A major proportion of lime is replaced by quarry fines.
- •
The superplasticizer reduces the water demand and increases mechanical strengths.
- •
The optimal mix gives mechanical characteristics satisfying the EN 12859 standard.
