Wet Carbonation of BCSA vs. CEM I: Phase Assemblage, Structure and Reactivity towards SCM Applications

ce/papers, Volume 9, Issue 6, Page 600-607, October 2026.
Abstract Within the re‐CEM project (part of the priority program SPP 2436 Net‐Zero Concrete), we investigate wet carbonation as a CCU pathway to convert recycled cement paste (RCP) into supplementary cementitious materials (SCMs). The study links RCP composition to the structure of the amorphous Al‐Si gel formed during carbonation, the phase assemblage

Mechanochemical activation of mixed raw clays: Influence of grinding parameters on process efficiency and physicochemical properties

ce/papers, Volume 9, Issue 6, Page 1496-1508, October 2026.
Abstract Natural heterogeneous clays offer potential as alternative supplementary cementitious materials (SCMs) for CO2‐reduced binder systems due to their pozzolanic properties and global availability. Mechanochemical activation (MCA) has emerged as an alternative method to enhance the reactivity particularly of mixed 2:1 clays. However, the influence

Pozzolanic reactivity and strength activity index of mortar containing palm oil clinker pretreated with hydrochloric acid [PDF]

, 2019
Palm oil clinker powder (POCP) is an agro waste material that is often overlooked due to its low pozzolanic reactivity and contaminated with impurities and organic carbon. Therefore this study was proposed to enhance the pozzolanic reactivity of palm oil

Durability performance of a high‐performance fiber‐reinforced concrete for bridge applications

Structural Concrete, Volume 27, Issue 5, Page 7667-7679, October 2026.
Abstract This paper investigates the durability performance of a coarse‐aggregate high‐performance fiber‐reinforced concrete (HPFRC) developed as a cost‐efficient material solution for precast bridge applications. A comprehensive experimental program was conducted to assess the resistance of the material to the principal deterioration mechanisms ...

Mineral Carbonation of Mixed Industrial Residues for Enhanced CO2 Sequestration and Environmental Stabilization: The Role of Slag Composition and Industrial Symbiosis

Advanced Energy and Sustainability Research, Volume 7, Issue 9, September 2026.
Accelerated CO2 carbonation transforms mixed industrial by‐products, including bottom ash (BA), fly ash (FA), and steel slags, into a value‐added material. The carbonated residue is used as a filler for HDPE composites, promoting both carbon sequestration and circular resource utilization.
