Thanks all for your comments,

Witold Bogusz, apperciate the references, we used them to add extra entries from papers we didn't have already. We are now close to 200 soils with the potential to increase it to around 250 covering a wide range of plasticity index.

Hans Henning Stutz , in short yeah, we are looking for critical state soil parameters for soils with fall cone test results available too; we started the idea for this study with the objective to improve the methodology in the first paper below, but we have refocused the efforts towards a slight different goal, hence the original question.

The paper describing the methodology to obtain critical state estimates has a lot of shortcomings i.e. quantity and quality of lab data mainly. Murat Gülen produced some interesting data validating the methodology of that paper and it was one of the drivers for us to revisit the methodology. We have now improved the method to determine the critical state soil line slope thanks to recent progress, see a snapshot in the figure attached, the diamonds in the figure show the experimental solution and the curves are the trends defined by the fall cane test results. The work was developed by Robinson Andrés Giraldo Zuluaga

Thanks Hans,

Yeah I am aware of Prof. Shimobe's work and have been in contact with him via e-mail. My original plan was to make the database publicly available in an spreadsheet form. We have made a significant effort to digitise some very old papers and would like to save that time to those that could see some benefit in that work in the future. That been said, while building this database I have got some unwelcoming replies while asking for data directly to authors. I do not want to get in trouble. The paper once published will have the complete list of the papers we used to build our model. The paper might take a couple of years to be out. Will share updates in this post as more solid results are produced.

Dear Marcelo Llano

You can consider the data result shown in the following paper for Quaternary soils. The liquid limit for the soils has been determined using different methods including the fall-cone method.

Thanks Abbas J. Al-Taie . Do you have the penetration vs water content data in a table format for use in our research? Of course we will cite your paper when the data is used.

I have a large amount of fall cone tests on soil and tailings. What would be the contribution and benefit?

Thanks, Sebastian Quintero . The contribution would be an improved model for the interpretation of fall cone test results. We believe the model is robust enough to capture the behaviour of soils from a wide range of plasticity, including non-plastic soils. We will be trialling some cemented soils soon. Your contribution would be probably the database you comment about in a format that we could use easily and related info (ie Atterberg limits for each soil). Depending on the size of your database, we can discuss authorship in the resulting paper if that is of interest. Also open to proposals.
