Study on the Production of Chromite Refractory Brick from

To produce chromite refractory brick, it is pressed under a press of 400 tons, dried and fired at 1580?°C for fifty two hours. Then, the standard properties such as cold crushing strength, apparent porosity, apparent specific gravity, bulk density and water absorption that the chromite brick should possess were measured.

Bulk Density: Definition Calculation

Compaction. The volume of voids is found by adding the volume of water and the volume of air. When a sample of soil is compacted, its volume of voids decreases which decreases the total volume of the soil sample. This increases the bulk density of the soil. So as depth increases, bulk density increases.

Practice problems: Porosity and bulk density UC Davis

Porosity = V air + V water /V total = 118.2cm 3 /188cm 3 x 100 = 63% . 10. What is the particle density of a soil sample that has a bulk density of 1.55 g/cm3 and a porosity of 40%. Porosity = (1-(r b /r d) x 100 40 = ((1-1.55/r d) x 100 1.55/r d = 0.6 r d = 2.58g/cm 3.

Apparent density | Article about apparent density by The Free

Apparent density. 1. The mass per unit volume of in-place thermal insulation. 2. The mass per unit volume (or the weight per unit volume) of a material, including the voids which are inherent in the material.

Sintering behavior of waste serpentine from abdasht chromite

Sintering behavior of waste serpentine and high grade kaolin was evaluated in this paper. It was revealed that all the compositions start to melt at 1350 °C. WSK 25 samples had initial sintering temperature of 1150 °C, while initial sintering of both WSK 50 and WSK 75 occurred at 1200 °C.

The use of enriched Kimpersaisk chromite for producing

Enriched Kimpersaisk chromite in the composition of magnesite-chromite refractories satisfactorily sinters at temperatures of firing of 1650–1730°C and produces dense refractories with an apparent porosity of 12–13%.

Implementation of industrial waste ferrochrome slag in

However for 1300 °C the bulk density and apparent porosity improved, this behavior may be attributed to ceramic bonds being formed . At 1300 °C reactions between alumina, slag, silica and cement form a liquidus phase filling the interspaces among the constituents of castables.

Properties of Refractories – IspatGuru

Bulk density is generally considered in conjunction with apparent porosity. It is a measure of the weight of a given volume of the refractory. For many refractories, the bulk density provides a general indication of the product quality. It is usually considered that refractories with higher bulk density (low porosity) are better in quality.

Porosity Wikipedia

Porosity is a fraction between 0 and 1, typically ranging from less than 0.01 for solid granite to more than 0.5 for peat and clay. The porosity of a rock, or sedimentary layer, is an important consideration when attempting to evaluate the potential volume of water or hydrocarbons it may contain.

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.
