ASTM C20 - 00(2015) Standard Test Methods for Apparent,

3.1 Apparent porosity, water absorption, apparent specific gravity, and bulk density are primary properties of burned refractory brick and shapes. These properties are widely used in the evaluation and comparison of product quality and as part of the criteria for selection and use of refractory products in a variety of industrial applications.What is an Apparent Density (pb)? - Definition from,,Apparent density (pb) is the ratio between the apparent volume and dry specimen mass of a soil sample. The volume is limited by external specimen forces which include voids. Therefore, it is measured in kilograms per cubic meter (kg/m 3 ).Rock Types and Specific Gravity - Edumine,An online tool for rock types and specific gravity.

Overview of Refractory Materials - PDHonline

Important properties of refractories are: chemical composition, bulk density, apparent porosity, apparent specific gravity and strength at atmospheric temperatures. These properties are often among those which are used as ‘control points’ in the manufacturing and quality control process.chromite crusher ball mill da ase - royalcrescentgroup,what is the apparent porosity for chromite chromite crusher ball mill da ase - valcor. sample mills in zimbabwe, chromite processing equipment zimbabwe,crusher for chromite, that particular ball mill but,Effect of binder type and other parameters in synthesis,As the chromite content of the mixture increased, the bulk density and strength was found to decrease resulting from increase in open porosity. This effect was considered to result from the inability of densification of the system with increasing chromite content.
