| Abstract: | A new sand displacement method for the determination of the bulk volume and bulk specific gravity of refractory or other material is described. A gas porosimeter with a vertical U-tube manometer for the determination of pore volumes of materials is also described together with calculations of the possible errors. The porosities, bulk specific gravities, and calculated true specific gravities of 15 types of refractory bricks obtained by means of these two methods, and the usual water absorption method are tabulated for comparison. |
