I am using fly ash and slag in my blended mix designs that have amorphous contents. I read somewhere that we can create hkl phase for the amorphous humps of fly ash and slag separately and then use those hkl phases to figure out what percent of amorphous content of fly ash and slag has reacted in the hydrated cement paste? Just wondering if anybody knows about the procedure to create hkl phases in highscore plus software, which can then be used to for the analysis of blended hydrated cements?
You need two steps to do that:
1), create a phase using simple crystal structure, like cubic, with a initial a (say 1nm), do the Lebail fit (generally, you need a vey big W value for the profile, 50~200, to fit the wide hump of the amorphous content); after you model the humps for the fly ash, then
2) change the fit to hkl fit, now you have the scale for this phase.
3) beyond these two steps, you need to do the calibration to get the PFMs for HKL phase to carry the quantitative analysis, you can find the detailed steps in the tutorial of the HighScore plus.
Have fun.
Thanks a lot Xuerun for all your help, I'll follow the steps you suggested and will get back to you in case i need further help.
Dear Mr. Rajeev Roychand,
First of all, please prepare the reference data of your material, such the Powder Diffraction File (PDF) maintained by The International Center for Diffraction Data (ICDD). Furthermore steps, you can follow the complete instructions as written in manual instruction. Here is the manual instruction.
