- Abstract
- he paper under discussion (Díaz et al., 2021) investigated the application of machine learning techniques to relate the Casagrande percussion-cup liquid limit (LLCUP) with the fall-cone liquid limit (LLCONE) determined using the 30°–80 g British Standard (BS) fall-cone device (BSI, 2018) for low–medium plasticity fine-grained soils (having plasticity index values of <30% and which mostly classify as CL–ML and CL) sampled from a specific site in SE Spain. As reported in their paper, the experimental LLCUP data were obtained in accordance with the UNE 103103:94 standard (AENOR, 1994), which employs a percussion-cup device having ‘hard’ base material satisfying the same hardness and resilience specification ranges as those of the ASTM percussion-cup device (ASTM, 2017). The clay mineralogy of the investigated fine-grained soils was not reported in Díaz et al. (2021); however, as explained in Haigh (2012) and O'Kelly et al. (2020a), clay mineralogy does not majorly account for dissimilarities in LLCUP and LLCONE measurements for a given fine-grained soil; rather they largely arise due to the different mechanics of the percussion-cup and fall-cone test devices (O'Kelly et al., 2018; O'Kelly, 2021; O’Kelly et al., 2022), and also due to variations in the hardness/resilience of the cup base-material (being ‘soft’ or ‘hard’) (Haigh, 2012, Haigh, 2016). The LLCUP water content is associated with the soil's specific strength (i.e., ratio of remolded undrained shear strength su to saturated bulk density
