Concrete consumption greatly exceeds the use of any other material in engineering. This is due to its good properties as construction material and the availability of its components. Nevertheless, the present worldwide construction increase and the high-energy consumption for cement production means a high environmental impact. On the other hand, one of the main problem in iron and steel industry is waste generation and by-products that must be properly processed or reused to promote the environmental sustainability. One of these by-products are blast furnace slag. Cement substitution by slag strategy achieves two goals, raw materials consumption reduction and waste management. In the present work, four different concrete mixtures are evaluated. 25% cement is substituted by different blast furnace slag. Tests are made to evaluate the advantages and drawbacks of each mixture. Depending on the origin, characteristics and treatment of the slag, concrete properties change. Certain mixtures provide proper concrete properties. Stainless steel slag produces a fluent mortar that reduces the water consumption whit a slight mechanical strength loss. Mixture with electric arc slag furnace properties are better to the reference concrete (without slag) when slag is treated similarly to the cement.

In the current paper, we have determined the desulfurization ability of a CaO–MgO–SiO2–Al2O3 slag system using slag-metal equilibrium technique. The chemical composition of slag samples consists of Al2O3 in the range of 25–30 wt%, CaO/SiO2 ratio (0.8–1.6) and MgO (8–16 wt%). All the experiments are conducted at a temperature of 1773 K. The sulphur content in the slag as well as in metal after desulfurization reaction is analyzed using XRF (X-ray Fluorescence Spectroscopy) for calculating sulphur partition ratio (LS) of the slags. The influence of Al2O3, CaO/SiO2 ratio and MgO content on LS have been studied. It is observed that LS increase with an increase in CaO/SiO2 ratio and MgO content, but it reduces as the Al2O3 content increase in slag. Also, the amount of bridge oxygen ([BO]) represented by (O0) decreases with increase in basicity and MgO content. However, O0 increases with increase in Al2O3. It is witnessed that the experimental values closely fit with the values obtained from corrected optical basicity model.

Abstract Ground granulated blast furnace slag (GGBFS) is one of green construction materials that held benefits in producing sustainable and high-quality concrete. GGBFS is commonly used as supplementary cementitious materials in blended cement to reduce the need for Portland cement in mortar or concrete production. An overview of the utilization of GGBFS as partial cement replacement with regards to mortar and concrete properties is presented in this paper. The fresh properties of GGBFS mixes addressed include workability and setting time. While compressive strength, porosity, shrinkage, and resistance to sulfate attack are the reviewed hardened properties. Overall, various studies showed that incorporating GGBFS in mortar/concrete mixes significantly improves mortar/concrete properties depending on the GGBFS replacement ratios. It is anticipated that this review will provide valuable information for a better understanding of the fresh and hardened properties of GGBFS-blended mortar and concrete. Moreover, as there is a growing interest in optimal utilization of GGBFS in Indonesia’s cement and construction industry, this review paper intended to raising awareness of GGBBFS utility regarding its benefit for sustainable construction.
