Good Day,
is there anyway besides microscopy to measure/predict the hardness/grindability of clinker?
Ted Krapkat
Hello Shastrib,
The Bond Work Index is one practical method.
Regards,
Ted.

Some years ago I had some grindability testing done by Magotteaux.
Two separate tests were performed, the first was the SGI test which assessed the number of
revolutions within a test mill that were required to produce a surface area of
350 m2/kg. The second was a breakability test which assessed the height that a
steel ball must be dropped from to break a clinker nodule.
I don't know if this testing is still available but it was useful when grinding a number of different imported clinkers

Dear Shastri B
I have procedrue for clinker grindability test in excel formate. If u insert the require values it will give the Bonds work index. If u r interested please give your email id so that i can mail u procedure as well as calculations. Following is my mail id.
