The ultrasonic velocities and compressive strength of frozen and thawed iron ore are strongly influenced by the magnitude of porosity ami moisture content. The velocities and strength both increase as the porosity decreases or as the moisture content increases. Iron ore frozen is more homo173 geneous in its elastic properties than when it is thawed.
The effect of suction on the behaviour of iron ore has been studied from both physical and mechanical points of view. the porosity and the suction phenomena have been analysed using different experimental techniques. uniaxial compressive tests on partially saturated samples have shown that the suction is responsible for strength and cohesion improvement. considering the theory of partially ...
