Phlogopite Mica Under Acidic and Alkaline Conditions: Reactivity and Silicate Gel Formation

Journal of the American Ceramic Society, Volume 109, Issue 6, June 2026.
ABSTRACT Alkali‐activated materials (AAMs) produced using industrial residues offer a sustainable alternative to Portland cement, the production of which contributes nearly 8% of global CO2 emissions. However, commercial sodium silicate, commonly used as an activator, remains costly and energy‐intensive to produce, motivating the development of ...

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 ...

Co‐Calcination of Silicate or Aluminosilicate Network of Clay and Non‐Clay Minerals With NaOH: Physicochemical Insights

Journal of the American Ceramic Society, Volume 109, Issue 6, June 2026.
Effects of co‐calcination with alkali hydroxide on pure clay minerals (kaolinite, montmorillonite) and typical impure minerals (quartz, feldspar) are presented. Co‐calcining montmorillonite and quartz with sodium hydroxide improves their reactivity. Co‐calcining kaolinite with sodium hydroxide reduces its reactivity.

Technobiological Pathways for High‐CO₂ Capture Using Micro‐/Macroalgae: Genetic Engineering, Process Automation, and Value‐Added Bioproducts

Asia-Pacific Journal of Chemical Engineering, Volume 21, Issue 3, May/June 2026.
ABSTRACT Greenhouse gas (GHG) emissions have emerged as one of the most critical drivers of climate change; this is primarily due to high concentrations and long atmospheric life of carbon dioxide (CO2). For a significant amount of time, various biological processes such as microalgal cultivation, cyanobacterial systems, photosynthetic microorganisms ...

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.
