The specific gravity of all other materials are compared to water as a fraction heavier or fraction lighter density, no matter how small or large the fraction is For example, afromosia has a specific gravity (sg) of 0705 while ebony can have a sg of 112 (1120 kg/cum) As specific gravity is just a comparison, it can be applied across any units
NATIONAL SLAG ASSOCIATION nationalslagassocorg Page 6 The relation between weight per cubic foot and bulk specific gravity is shown in the accompanying graph Weight per cubic foot of blast-furnace slag may vary with the source of the slag but is reasonably uniform for a ,
Blast Furnace Slag - Material Description ORIGIN In the production of iron, iron ore, iron scrap, and fluxes (limestone and/or dolomite) are charged into a blast furnace along with coke for fuel The coke is combusted to produce carbon monoxide, which reduces the iron ore to a molten iron product
as specific gravity vary by type of slag and by source The producers in the particular proj-ect area should be consulted for data on their specific product Steel slag should be tested for expansion (ASTM D 4792 or other approved method) prior to use as a base material for pavement Size and Grading Requirements Sub-base Applications
Ground-granulated blast-furnace slag (GGBS or GGBFS) is obtained by quenching molten iron slag (a by-product of iron and steel-making) from a blast furnace in water or steam, to produce a glassy, granular product that is then dried and ground into a fine powder
Proportioning Concrete with Slag Cement Concrete mixtures containing slag cement should be proportioned according to ACI 2111 The specific gravity of slag cement ranges from 285 to 294, depending on the slag source, as compared to 315 for portland cement
The specific gravity of slag cement ranges from 285 to 294, depending on the slag source, as compared to 315 for portland cement The difference in specific gravity means a greater volume of slag cement will be used to replace the same mass of portland cement
granulated blast-furnace slag is the granular material formed when molten iron blast furnace slag is rapidly chilled by immersion in water It is a granular product with very limited crystal formation, is highly cementitious in nature and, ground to cement fineness, and hydrates like port land cement The specific gravity
Specific gravity of an aggregate has several definitions to account for the treatment of the surface voids of the aggregate Based on the type of void being considered the specific gravity is defined as bulk, apparent and effective Apparent Specific Gravity (G
Dec 18, 2010· Slag cement should be substituted for Portland cement on a one-to-one basis by mass Specific gravity of slag cement ranges from 285 to294, depending upon the slag cement source-as compared to 315for Portland cement The difference in specific gravity means a greater volume of slag cement will be used to replace the same mass of Portland cement
1) NTP - Normal Temperature and Pressure - is defined as air at 20 o C (29315 K, 68°F) and 1 atm ( 101325 kN/m2, 101325 kPa, 147 psia, 0 psig, 30 in Hg, 760 torr) Since specific gravity is the ratio between the density (mass per unit volume) of the actual gas and the density of air, specific gravity ,
Standard Value of Specific Gravity of Cement The specific gravity value of portland cement is generally around 315 while the specific gravity value of portland-blast-furnace-slag and portland-pozzolan cements may have specific gravities near 290 Portland Cement Association (PCA) (1988)
(15) It is more porous, with lower specific gravity and higher absorption, than air-cooled nickel slag Copper Slag Air-cooled copper slag has a black color and glassy appearance As a general rule, the specific gravity will vary with iron content, from a low of 28 to as high as 38
