i work in a cement company, too
for the silica determination by XRD, you can have a look here

http://www.osha-slc.gov/SLTC/silicacrystalline/smithdk/index.html

for the other questions ... do you want to 'determinate CO2 in cement' by
XRD?
perhaps you want to determinate free lime in cement ...

best regards

Oggetto: Quartz and others


 work in a cement company and I have a Philips XRD 1800. I want to
determinate quartz in limestone. I would like to deteminate CO2 in cements
and CaCO3 in limestone too. I am new in XRD utilization so I require
detailed answers.

Is another member who work in a cement industry?

Best regards
