What is it about?
The paper presents a new methodology to assess the unconfined compressive strength (UCS) in cement-based stabilised soft soils with a high water content (w>wL). The new method depend on the binder content and the liquidity index.

Why is it important?
The binder content and the liquidity index are identified as fundamental parameters. A simple and expedite method based on normalisation by the liquidity index is proposed. This method was successfully validated for a wide range of chemically stabilised soft soils, subjected to zero or small curing stresses, thus demonstrating its versatility.
Perspectives
In authors' opinion this new method can be applied satisfactory in field practice. Moreover, applying the generalised relationship of the method, data from only one test condition are required to assess the UCS for other possible combinations of binder content and liquidity index.
