Closure to “Fines Classification Based on Sensitivity to Pore-Fluid Chemistry” by Junbong Jang and J. Carlos Santamarina

The proposed new fines classification system is an attempt to address the demands of geotechnical engineers who require a methodology that systematically characterizes fines for diverse geotechnical applications. We received six official discussions, three direct contributions, and several other personal communications regarding procedures and data analysis. Overall, contributors welcomed the proposed methodology for its repeatability, its enhanced discrimination and clustering capabilities, and its ability to identify differences in particle-particle interaction associated with pore-fluid changes. This closure benefits from the input provided by all of these contributions, and is organized in three sections: data, test procedure, and interpretation. - See more at: http://ascelibrary.org/doi/10.1061/%28ASCE%29GT.1943-5606.0001694#sthash.IMgJt2FU.dpuf
