Percent Porosity Determination

I need to determine less than 3% porosity. Can A-Scan do this for me? If so how calculated? Thanks!

  • A rigorous way to do this is to build a collection of reference samples that span the range of porosity and thickness you expect to encounter. Make amplitude measurements on these samples using your A scan technique. From these measurements you can construct attenuation vs porosity vs thickness curves that will enable you to quantify porosity using your A-scan technique. Note that these curves will only be valid for the frequency used to create them. Getting good porosity samples can be a challenge!
