EAF is a by-product of oxidation of old steel during the production of steel in an EAF.
Cold crushing strength (CCS) is the capacity of a material to withstand axially directed pushing forces. ... At 1300 °C reactions between alumina, slag, silica and cement form a liquidus phase filling the interspaces among the constituents of castables. Fine particle size distribution of the microsilica mixture also helped in improvement of ...
Due to the potential to advance the concrete industry towards the development of sustainable construction materials, there has been a growing interest in researching the combination of geopolymer binders with recycled aggregates (RA) to address the challenge of utilizing CDW and industrial waste [9], [10], [11].On one hand, …
Slag cement use can be traced to the 1700s when the material was combined with lime to make mortars. The first United States production was in 1896. Until the 1950s, granulated slag was used in the manufacture …
The American Concrete Institute (ACI) has recently published ACI 233R-17 Guide to the Use of Slag Cement in Concrete and Mortar. As slag cement use is rising in the U.S., understanding how slag cement works best in various situations is increasingly …
Concrete's compressive strength was found to be on par with or higher than that of regular concrete when less than 40% copper slag was used in place of fine aggregate [26].Copper slag has the ability to replace admixtures in concrete and mortars [27].With CS and cement by-pass dust as stand-ins, the strength of cement mortars …
Electrolytic manganese residue (EMR) and barium slag (BS) are important industrial solid wastes. EMR is a byproduct of the electrolytic manganese-metal process, which is produced by acid leaching, neutralization, and pressure filtration of manganese carbonate powder [1], [2].BS is a solid waste produced in the process of preparing …
The slump value decreased from 180 mm to 60 mm with steel slag usage and concrete density increased by 10.2%. With the increment in the applied load, the …
Slag cement use can be traced to the 1700's when the material was combined with lime to make mortars. The first United States production was in 1896. ... and is processed …
This disparity can be attributed to the porous microstructure of steel slag. The crushing value of BOFS (12 - 15%) is equal to or slightly lower than that of natural aggregates such as granite (17%) and limestone (13.9%). ... the mechanical performance of concrete using steel slag aggregates would increase proportionally with higher ...
Concrete specimens were prepared with steel slag and crushed limestone aggregates. The concrete mixtures were prepared with a cement content of 400 kg/m 3 and water to cement ratio of 0.40. Steel slag aggregate concrete mixtures were prepared with steel slag aggregate to total aggregate ratios of 0.45, 0.50, 0.55, 0.60 and 0.65.
The total element concentrations in the ladle slag and cement were determined by ICP-MS and FAAS after microwave assisted digestion, using a mixture of nitric, hydrochloric and hydrofluoric acids, and the addition of H 3 BO 3 for complexation of fluorides (Zuliani et al., 2013). 2.5.
