Anybody who opens and reads Kempe's Engineers' Yearbook does.

I was sick that day in school when we covered it also.

Here's a start, in addition to PWslack's suggestion which would probably be the better way to research this.

ROCK HARDNESS CLASSIFICATION - MOHS SCALE

What defines the hardness of rocks and minerals

Hi Pravin; assuming you are looking to design foundation, the SBC for BCS is taken as 100mPa in general. Morum with water or what are you refering to? If you mean with water then go with SBC:100mPa else you can take upto 180.

For the Hard Rocks it varies - better to have a Strata test done - Granites in our country vary too much - for example in southern AP - Uncracked Silica Granite test yielded upto 800mPa while similar looking granite had less than 450. So I cant give you correct figures for granites - your designs shall be based on actual tests. Assumptions can be dangerous some times.
