“…Now, Blast furnace Slag could also be used in concrete as fine aggregates. It was found through experimentation that GGBFS/sand ratio was the governing criteria for the effects on the strength and durability characteristics [14]. While strength decreased in some percentage, its replacement of sand particles had positive effects on durability characteristics of concrete.…”

“…Thus it can be used in low and normal strength concretes. It was suggested an approximate replacement of sand by 50% [14], but the only condition one has to keep in mind while using slag as a replacement for fine aggregate was to use a sub-type sand which is finer than the slag particles. Keeping the results in mind, the use of slag as a replacement for fine aggregates can be allowed in building units like concrete bricks or blocks, where durability is a more important criterion than strength [7].…”

Abstract-This paper aims at bringing a literature review on the uses and properties of popular industrial and mineral byproduct slag. At the present, most industrial slags are being used without taking full advantage of their properties or disposed rather than used. The use of slag in replacing Portland cement by GGBFS is not very common. The traditional way to utilize metallurgical slags in cementing materials is to partially replace Portland cement. The practice of using such mineral admixtures in construction will reduce the need of portland cement and its use in various parts of the world, thus greatly reducing the amount of pollution and pave a way for a cleaner and more economical construction material, of which India is in a great need.The literary investigation was carried out on different forms of slag used in construction, i.e. slag aggregates, ground granulated blast furnace slag (GGBFS) and slag mixed with clinker in cement production. Many different properties were examined during the literature review, all segregated into separate categories based on the type of usage, particle size and chemical composition. The base samples ranged from cement sample to meter cubes, beams and concrete cubes. The properties investigated from various sources of literature were hydration, reactivity, hydraulic power and slump loss. Also properties related to durability and environmental effects like cabonation depth, chloride resistance, sulphate resistance, percentage of water absorption, heat resistance and resistance to freeze and thaw cycles are also discussed. Its activation with innovative methods and certain reasons were found out which attributed to such behaviour such as glass content, microstructure, pH nature, pore size etc.The behaviour of concrete samples were also investigated with some agents, i.e. samples with some extra chemical admixtures, air entraining agents. Also differentiation was done on the basis of formation of slag aggregates, i.e. the variation in properties of slag based construction materials vary when slag is created employing different techniques. The investigation will also explain the different problems faced by civil engineers in using slag as a major component in building materials.

“…In general, some of the steel slag is used internally by steel companies as a flux and returned to the blast furnace for secondary smelting or as a raw material for ironmaking. In addition, many scholars have conducted numerous studies on topics such as the production of agrochemical fertilizers [3], the production of adsorbents for wastewater treatment [4,5], the chemical leaching extraction of rare elements [6], and the production of cement [7]. Due to the huge output of steel slag, it is necessary to develop other ways to utilize steel slag.…”

Abstract:In this study, SiO 2 -Al 2 O 3 -CaO-MgO steel slag ceramics containing 5 wt % MgO were used for the preparation of ceramic bodies, with the replacement of 5-20 wt % quartz and feldspar by fly ash. The effect of the addition of fly ash on the sintering shrinkage, water absorption, sintering range, and flexural strength of the steel slag ceramic was studied. Furthermore, the crystalline phase transitions and microstructures of the sintered samples were investigated by XRD, Fourier transform infrared (FTIR), and SEM. The results showed that the addition of fly ash affected the crystalline phases of the sintered ceramic samples. The main crystal phases of the base steel slag ceramic sample without fly ash were quartz, diopside, and augite. With increasing fly ash content, the quartz diffraction peak decreased gradually, while the diffraction peak intensity of anorthite became stronger. The mechanical properties of the samples decreased with the increasing amount of fly ash. The addition of fly ash (0-20 wt %) affected the optimum sintering temperature (1130-1160 • C) and widened the sintering range. The maximum addition amount of fly ash should be 15 wt %, for which the optimum sintering temperature was 1145 • C, water absorption was 0.03%, and flexural strength was 43.37 MPa higher than the Chinese national standard GBT 4100-2015 requirements.

“…3) There are a number of steel slag utilization methods, which are directed to the use of certain components or characteristic in steel slag, such as utilization in steel enterprise interior (for waste steel and CaO), utilization for production of cement and concrete (for CaO and SiO 2 ), 4) November 26, 2016) A new SiO 2 -CaO-MgO-Fe 2 O 3 system ceramics, namely pyroxene ceramics in this paper, was put forward for efficiently utilizing the steel slag. The prepared ceramic with 30 wt% of steel slag has excellent properties with flexural strength of 107 MPa and water absorption rate of 0.045%.…”
