Alkali-activated composites based on slags from iron and steel metallurgy [PDF]

Metalurgija, 2009
Slag as a secondary raw material from metallurgy is most often heaped in slag disposal areas without any profit. This paper deals with alkali activated slag from iron and steel production which can be used in the building industry.

Recovering Critical Elements From Wastewater for Battery Materials: A Review

Rare Metals, Volume 45, Issue 7, July 2026.
ABSTRACT Driven by global carbon neutrality goals, the transition toward a circular economy and sustainable resource management has become increasingly imperative. Given the indispensable role of battery technologies in modern energy storage systems, strategic elements such as lithium (Li), cobalt (Co), and nickel (Ni)—identified by the European ...

Pedogeomorphology of semiarid soils of Ulu Peninsula, James Ross Island, Antarctica

Soil Science Society of America Journal, Volume 90, Issue 4, July/August 2026.
Abstract Located in a transitional climatic zone of the Antarctic continent, James Ross Island (JRI) presents soils that reflect complex interactions between lithology, topography, and pedogenesis. This study characterizes soils along a toposequence to evaluate how slope position and parent material control soil properties and weathering patterns in a ...

Effects of three different types of fibers and dosage on the properties of alkali-activated copper slag–slag cementitious materials

Scientific Reports
The use of copper slag instead of part of the slag to prepare alkali-activated cementitious materials can achieve the resource utilisation of copper slag, but alkali-activated copper slag–slag composite cementitious materials have the disadvantages of ...

Alkali Activated Slag Mortars Provide High Resistance to Chloride-Induced Corrosion of Steel

Frontiers in Materials, 2018
The pore solutions of alkali-activated slag cements and Portland-based cements are very different in terms of their chemical and redox characteristics, particularly due to the high alkalinity and high sulfide content of alkali-activated slag cement ...

Synergistic Effect of Ladle Furnace Slag and Biomass Bottom Ash in Alkali‐Activated Binders

Journal of the American Ceramic Society, Volume 109, Issue 7, July 2026.
This study investigates the synergistic co‐activation of ladle furnace slag (LFS) and biomass bottom ash (BBA) in alkali‐activated binders. Results indicate that 75 wt% BBA maximizes mechanical strength, reaching 11.1 MPa in compression after 90 days. Amorphous silica from BBA acts as a chemical buffer, mitigating slag expansion while forming a stable ...

Reaction degree and morphology of cement-lithium slag slurry using different curing methods

Shuili Shuiyun Gongcheng Xuebao, 2018
Performance of lithium slag concrete is affected greatly by the reaction degree of lithium slag. For this reason, the reaction degree of lithium slag in cement-lithium slag is tested by HCl solution method.

Resistance of Alkali-Activated Slag Concrete to Chloride-Induced Corrosion [PDF]

Advances in Materials Science and Engineering, 2015
The corrosion resistance of steel in alkali-activated slag (AAS) mortar was evaluated by a monitoring of the galvanic current and half-cell potential with time against a chloride-contaminated environment. For chloride transport, rapid chloride penetration test was performed, and chloride binding capacity of AAS was evaluated at a given chloride.
