Granulated Slag

Granulated Blast Furnace Slag is a cement substitute that improves durability and also the environmental credentials of concrete mixes. It is a by-product of the iron-making industry. For every tonne of GBS used in a concrete mix, the embodied CO2 levels are reduced by around 900 kg compared to the use of one tonne of traditional Portland Cement.

Ground Granulated Blast Furnace (GGBF) Slag Used in

Blast furnace slag is nonreactive in a high alkali environment, such as concrete and soils. Blast furnace slag concrete can be reliably pumped when the slag is supplied to the ready-mix production in a saturated condition. Use of the cementatious properties of ground granulated blast furnace (GGBF) slag was reported as early as 1774.

Converting Granulated Blast Furnace Slag into Fine Aggregate

glassy sand with 97 % of the solid granulated slag particles less than 4 mm as shown in Figure 1. Granulated BF slag is regularly used by cement industry for making portland slag cement; however conversion of this slag into fine aggregate and use as replacement of river sand is an innovative and novel approach to recycle slags.

Ground granulated blast

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.Ground-granulated blast furnace slag is highly cementitious and high in calcium silicate hydrates (CSH) which is a strength enhancing

GENERAL INFORMATION Iron Steel Slags

GRANULATED - Molten slag is chilled quickly to form a glassy, granular product. This process is the most rapid of the cooling processes and little or no crystallization occurs. The granulated slag may be crushed and screened, or pulverized for various applications. GRANULATED SLAG USES - Highway base and subbase, pipe

Granulated nickel slag is essentially an angular, black, glassy slag sand. Gradation : No specific data were identified, but no problems are anticipated in producing the appropriate gradation. Unit Weight : The unit weight of crushed air-cooled nickel slag tends to be as high as 3500 kg/m (3) (219 lb/ft (3) ).

Utilization of carbonated and granulated steel slag

Jun 01, 2015Jun 01, 2015Up to now, the main methods of using steel slag were used as sinter material, hot metal dephosphorizing agent, waste water treatment materials, reclamation of waste steel, concrete admixtures, CO 2 capture, agriculture and aggregate in construction etc. Typically, the crushed steel slag was used as coarse aggregate directly, for example, all
