Key Features: If the volume is unit then, Bulk Density= Mass. Unit in kg/m 3 or lb/ft 3. In this definition, the volume contains both the aggregates and the voids between aggregates particles. The approximate bulk density of aggregate that is commonly used in normal-weight concrete is between 1200-1750 kg/m3 (75-110 lb/ft3) .

Physical properties testing. Physical properties are widely used to classify refractory materials. 1. Bulk density. It's a measure of a product's overall quality. The weight-to-volume ratio, expressed in g/cm3. 2. Porosity. It is the ratio of the volume of its pores to the overall volume of the body.

1. Bulk Density. The Bulk Density of a refractory is the ratio of weight (or mass) to volume. It's expressed in pounds per cubic foot (lb/ft 2) or kilograms per cubic meter (g/cm 3). 2. Cold Crushing Strength. Often referred to as CCS, Cold Crushing Strength measures the maximum stress needed to crush a refractory sample to …

Grain morphology also affects the state of bulk density in granular systems, as it impacts how particles slip, rotate and rearrange under arbitrary stresses [3,4]. In return, this impacts local and collective processes ranging from contact deformation and grain fracture to volume change and critical density-stress state relationships [ 5 – 7 ].
