  • A review on lead slag generation, characteristics, and ...

    The compressive strength of concrete prepared from lead slag was superior to that of ordinary concrete. In addition, concrete containing lead slag absorbed gamma radiation more, which made it different from ordinary concrete. Saikia et al. (2012, 2008) used lead slag to replace 25–35% of the fine aggregate in the preparation of the cement ...



  • Study on the application mechanism and mechanics of steel ...

    Enormous demand and production for cement and concrete lead to a sharp increase in carbon dioxide emissions, and alternatives to cement are urgently needed to produce green cement and concrete. This paper is aimed at exploring the feasibility of using steel slag (SS) and granulated blast furnace slag (GBFS) to prepare cementitious materials. Mineral phases of SS are determined and observed by ...


  • A review on lead slag generation, characteristics, and ...

    In general, cement-stabilized sand is used in the pavement base. Lead slag is a black granular material similar to sand; it has a high specific gravity of 3.6–3.9 g/cm 3 owing to its high content in iron oxide. The lead slag has a better granularity and grain size curve compared with sand (Buzatu et al., 2015).


  • Resources | SCA - Slag Cement Association

    The SCA is proud to promote the use of slag cement to ready mix producers and industry professionals who understand the durable and sustainable benefits of slag cement in producing high quality concrete. Professionals agree, where other cementitious materials fail to produce consistent results, slag cement produces a more workable concrete with ...



  • Lead Slag - an overview | ScienceDirect Topics

    Lead slag (Prem et al., 2018), copper slag (Gursel et al., 2019; Shi et al., 2008), iron slags (Jiang et al., 2018; Yi et al., 2012) and nickel slag (Papadakis et al., 2002) were utilized as aggregates in high-density concrete applications, such as road pavements and radiation shielding walls. The underlying premise for the suitability of slags ...


  • Composite materials with primary lead slag content ...

    The presence of the primary lead slag as aggregate substituent in concrete, along with steel shot and barite, enhances the density and shielding efficiency against gamma radiation for Ir 192, Cs 137, Co 60 radioactive elements with average gamma energies of 0.37 MeV, 0.662 MeV and 1.25 MeV. The results showed that even the presence of primary ...


  • Utilization of iron and steel slag in building construction

    concrete and changes in the properties of concrete with steel slag aggregates by replacing the use of natural aggregates. Hadadi, et.al, (2017) concluded that the replacement of the coarse aggregate by steel slag by 60% is beneficial for the better workability and strength. Daset.al, (2007) discuss that the slag are generated as waste


  • Cupola slag reutilization for sustainable waste management ...

    This suggests the use of industrial waste (cupola slag) for a mainstream application rather than landfilling, which is a step towards sustainable waste management. The use of cupola slag for green concrete making has been discussed by Mistry and Varia . The coarse aggregates have been replaced by crushed cupola slag for making concrete.


  • A review of steel slag usage in construction industry for ...

    About 100–150 kg SS is co-produced for 1000 kg steel, and a huge amount of slag storage is generated annually worldwide. Despite the problems associated with SS, this storage should be evaluated for sustainable development, and it has many possibilities for use in the cement and concrete industry (Lizarazo-Marriaga et al. 2011). Millions of ...


  • Steel Slag - an overview | ScienceDirect Topics

    The incorporation of air-quenching steel slag of 0.315–5 mm (in which the content of Fe 1-σ O is over 30%) into concrete to fabricate mechanically sensitive concrete was investigated by Li et al. in 2005 [21]; subsequently, Jia performed a systematic study of this concrete (as shown in Figure 2.14) [23,50].


  • EG0800309 Attenuation of Gamma Rays by Concrete – Lead Slag ...

    The density of the used lead slag is 4.68 gm/cm3.

The sand was partially replaced by lead slag. The percentages by volume of lead slag / total fine aggregates were 0, 5%, 10% ...



  • Effect of 30% Ground Granulated Blast Furnace, Lead and Zinc ...

    This paper investigates the effects of using Ground Granulated Blast Furnace Slag (GGBFS), Lead Slag (LS) and Zinc Slag (ZS) as replacement for sand on the strength of concrete. Compressive strength, flexural strength, water absorption and density were tested at 14, 28 and 56 days. In this study, a total of 40 concrete samples, including Pozzolanic Portland Cement (PPC), GGBFS, LS and ZS ...


  • slag in concrete Topic - American Concrete Institute

    The use of slag in concrete has several benefits, including reduced energy, reduced greenhouse gas emissions, and reduced use of raw materials. Various types of slag are produced: - Blast-furnace slag—The nonmetallic product, consisting essentially of silicates and aluminosilicates of calcium and of other bases, that is developed in a molten condition simultaneously with iron in a blast furnace.


  • Effect of fly ash and slag on concrete: Properties and ...
