Uniaxial Compressive Strength - an overview ...

The uniaxial compressive strength of a rock under static loading often decreases with an increasing temperature at which the rock has been heat-treated before strength testing. This conclusion is drawn from a great number of experiments [1,2,4,8,9,11,17–19].The higher the temperature is, the lower the strength. Some results for uniaxial compressive strength σ c and tensile strength σ t ...

British Library EThOS: The reduction of some iron ores

The compressive strength was decreased because of the inherent weakness of both wustite and iron, which readily deformed plastically at moderate temperatures. The low grade ore, Oxfordshire, differed from the high grade ores in that the iron-bearing materials were calcium ferrites. The specimens after all reduction stages showed a contraction.
