We are currently using Potassium Dichromate (inorganic salt) for testing for Organic content in soils as per BS1377:1990.
Does anyone know of a safer alternative to this chemical which has/can be successfully proven to have neglible effects on the test results?
Hi everyone, i'm a soils technician from England working to BS1377 standards.
We are trying to develop a method to accurately judge the CBR value of recompacted soils to pre-determine seating loads. We have trid a hand penetrometer but found it to be too inaccurate. Any suggestions?
