Chapter 1: Introduction
1.4 Aims and Objectives of Research
The aim of this study is to compare the Ring-loaded strength disc test to that of the Bond Work Index grindability measure and the Mode I fracture toughness test. This is achieved by testing a range of rock materials using each of the three test methods and comparing the results. The relationships derived then allows a prediction of either the Bond Work Index or the Mode I fracture toughness of a rock directly from ring-loaded strength disc tests.

Dear Dr Rock
can you advise what rock is better to give my grandchildren as a present, would you advise Blackpool rock or Southport rock as i have been told one of them has less sugar content so it won’t rot their teeth
could you please reply as soon as possible as it’s their birthday next week

I don’t think you seem to realise you can’t afford a ipud on a pension and I was waiting for a response from the rock expert “Dr Rock” himself

Hello Mick, i mean Hilda.
Glad you dropped by.
I have to say that any kind of rock would be appreciated by your grandchildren, to be honest I am not sure you should be focusing on where the rock comes from but more what flavour. Some people go for minty ones and others fruit. I like the fruity ones.
You could move away from confectionary and get them some real hard core rock. Wollastonite for example:

I hope that helps Hilda

Dr Rock
