Download scientific diagram The XRD pattern of the steel slag from publication Characteristics of Pavement Cement Concrete Incorporating Steel Slag Powder After thermal braising and magnetic
Steel production has been targeted to be higher than as of now in future and the generation of slag will also be high Steel slag is presently used in various fields such as in construction Lam
In this study the kinetics of aqueous carbonation of steel slag in an atmospheric three phase system containing steel slag water and CO 2 gas was studied Also some factors likely affecting this process were investigated such as reaction time and temperature steel slag particle size d CO 2 flow rate and the mass ratio of liquid to solid L/S

Steel slag is a waste discharged from the iron and steel smelting process which has the characteristics of large output high temperature complex chemical composition and poor stability
is the lack of slag chemistry and viscosity control In many cases the slag tended to be too stiff to sustain an adequate foam The following discussion will attempt to provide a better understanding on the key factors that control slag foaming in stainless steel making There are basically two requirements for slag foaming C Steel and
Abstract Steel slag is a kind of alkaline solid waste produced in the process of steel production In China the annual steel slag production is very large but the utilization rate is only 20% Therefore technologies disposing steel slag effectively need to be developed In traditional resource utilization technology steel
Argon oxygen decarburization AOD slag which is generated during the stainless steel refining process is a by product of the steel industry Li et al 2017a AOD slag is a kind of alkaline material characterized by a dominance of Ca bearing silicate phases and the minerals include γ dicalcium silicate fluorite and magnetite as well as traces of f CaO f MgO
In Vietnam due to the severe environmental impact of steel slag and the fact that a large volume of excess steel slag has limited employment only Ba Ria Vung Tau province in Southern
The collected steel slag was initially grinded into fine particles using a kitchen mixer grinder for 20 min After grinding average steel slag size was obtained as approximately 100 µm in size and flaky in shape 2 The slurry was prepared by mixing the dry fly ash and potable water in the ratio of 65 35 respectively by mass
The problem of steel slag could be solved by expanding the utilization ways of steel slag At present steel slag has been used in the production of cement the construction of urban roads and the production of fertilizer Fronek et al 2012; Jiang et al 2018b; Shi and Qian 2000; Wang and Cai 2006 In developed countries the utilization rate of steel slag is close to
Other researchers [16] carbonated the steel slag powder with vol% CO 2 in aqueous environment for 1 h in which 12 wt% CO 2 uptake was gained Addition of 10 % carbonated steel slag in the cement mortar yielded 23 % increase in the compressive strength at 28d compared with the cement mortar mixed with 10 wt% uncarbonated steel slag
Steel production has been targeted to be higher than as of now in future and the generation of slag will also be high Steel slag is presently used in various fields such as in construction Lam

Fig 5 shows the 3 and 7 d carbonation depth test diagrams of the SC 2 samples For 3 d carbonation a large area inside the sample is observed to still be pink owing to the alkalinity of the steel slag; the phenolphthalein is observed to have turned red reflecting the fact that the internal steel slag carbonation is incomplete; and the
To solve the problem of difficult utilization of steel slag the liquid steel slag was modified and the air quenching granulation process was carried out to make steel slag into a value added end product air quenching granulated steel slag The granulated slag was tested to analyze the variation rule of slag properties under different modification conditions Based on
