I am working on a project that consists of constructing a cap for a waste landfill. The local material consists of clayey minerals that include smectite. Smectite is very swelling material,thus we need to mix the local material with borrowed ones to limit its smectite. I wanted to run X-Ray diffraction test to measure the smectite content quantitatively. It seems that this is not an easy job,and most of the companies just conduct qualitative XRD test. My questions are:
1-Does any body have any similar experience that could share with me?
2-Do you know any company that could run the XRD testquantitatively?
3-Is there any other technique that I could use?

From my research experiences, I think that you don't need to perform these kind of tests only to quantify the amount of smectite in your soil. You must just focus on the Swelling properties of your soils. In the past I had used long time to identify the mineral properties of swelling soils in Senegal, west africa and what I think that if you only want to reduce the swelling properties of these soils, the solutions you had taken to mixe the swelling soils with an no active one is good, also using geotextile as barriers is also good. Just identify the magnitude of the swelling pressure and also try to identify these soils by simple soils charts as casagrande tables, etc.
