In this review, steel slag usage in the cement and concrete industry and its environmental
effects were examined. Also, its physical and chemical structure, its effect on the …

Steel slag is the main waste product in the steelmaking process. Because of its chemical
composition and technical properties, it can be reused as raw material in steel plants and …

Steel slag inhibits the early-age hydration of cement. However, its mechanism is still unclear.
In this paper, the early-age hydration kinetics and the evolution of the solid phases, aqueous …

Steel slags are by-products generated in high volumes in the steel industry. Their main
constituents are calcium, silicon, ferric, aluminum, and magnesium oxides. Larnite, alite …

Slag is a waste product from the pyrometallurgical processing of various ores. Based on
over 150 published studies, this paper provides an overview of mineralogical and …

Steel slag has been used as supplementary cementitious materials or aggregates in
concrete. However, the substitution levels of steel slag for Portland cement or natural …

The current utilization rate of steel slag is only 22% in china, far behind the developed
countries. At present, the amount of slag deposited in storage yard adds up to 30Mt, leading …

Autoclaved aerated concrete waste (AACW) is a common low-strength cement-based
construction and demolition waste, which is currently disposed by landfills and hard to be …

In this study, five types of steel slags with different free CaO (f-CaO) and MgO contents were
used as mineral admixtures to prepare concretes with W/B ratios of 0.5 and 0.35. The …

Due to its low hydraulic reactivity, ladle slag is currently underutilized with nearly 80% of
annual generation is either landfilled or dumped. This work investigates the joint activation …
