Abstract

Sedigraph analysis, nitrogen adsorption method and mercury porosimeter test. The fine grained material from weathered granite has specific surface area values of for greater than those corresponding from silty till and clayey vein. The results of the mercury porosimeter test show a strong increase in the cumulative pore volume and pore area in pores with diameters less than 1 micrometre, as compared with the corresponding pore sizes in the finest powder of a similar grain size distribution from artificially crushed granite
