Hi Madam. I wish to seek for some advice from Madam regarding following cases. I encountered a case as follow: PSD showing SILT content is higher (55%) as compare to the CLAY content (15%); but, Atterberg Limit result showing it is CLAY of low plasticity, CL (LL=33%, PL=21%, PI=12%). In this case, how should i do the naming and which result should i refer to? Thanks in advance Madam 😊
Hi, sorry for a late reply. I believed that you’ve conducted a wet sieving & hydrometer test for PSD. However, referring to BS 5930, it stated that ‘Fine soil should be described as either a “SILT” or a “CLAY” depending on the plastic properties’. So, the best is…. refer to Atterberg limit test results. Perhaps this might help you. 🙂
Thank you Madam for the sharing. Very clear explanation. 🙏
Thank you madam, simple and easy to understand 👍🏼
Glad it was helpful!
