Dec 23 2008 We have been using 3000 ohm meters for our crushed rock values as a typical from examples in IEEE80 However we did tests of our crushed rock and came up with about 9600 ohm meters Our tested crushed rock is 1 1 4 in size and we wetted it prior to taking measurements.

Dec 03 2018 The pore size distribution as interpreted by BJH theory (Fig 7) show that ironstone facies and silty shale facies have larger peak at 4 nm (40A ) to 10 nm (100A ) while other samples have limited pores below 20 nm (200A ) and most of the pores.

Size on uniaxial compressive strength This paper presents the results from CRF samples that were prepared using the same mix design and then cast into moulds with diameters of 150 240 300 and 400 mm The laboratory testing also allowed a better understanding of the effect of particle size distribution upon the overall strength of a rock fill.
