Effect of fluorite addition on the reactivity of a calcined treated spent pot lining in cementitious materials

Cement, 2023
Treating SPL by the low caustic leaching and liming process generates an inert nonhazardous residue called LCLL Ash and a fluorite byproduct Calcined LCLL Ash that is ground into a fine powder demonstrates pozzolanic behavior in cement. The effect of the

Field‐Validated Predictive Model for Strain Modulus of Dispersive Clay Stabilized With a Waste Calcium Composite for Sustainable Subgrade Design

Engineering Reports, Volume 8, Issue 7, July 2026.
A field‐validated predictive model accurately estimates the strain modulus of waste calcium composite‐stabilized dispersive clay. The model provides a reliable, sustainable, and cost‐effective tool for subgrade design, reducing dependence on extensive field testing while improving pavement performance.

Valorization of mud from Fergoug dam in manufacturing mortars

Case Studies in Construction Materials, 2016
The production of calcined mud, with pozzolanic properties, from the large quantities of sediments dredged from Algerian dams, could be a good opportunity for the formulation of high performance mortars and pozzolanic concretes, with lower costs and less

Recent developments in reactivity testing of supplementary cementitious materials

RILEM Technical Letters, 2021
Identification and rapid characterization of novel supplementary cementitious materials (SCMs) is a critical need, driven by shortfalls in conventional SCMs. In this study, we present a discussion of recently developed reactivity tests – the R3 test, the

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 ...

Carbon Dioxide Uptake and Storage in Construction Materials: Mechanisms, Theoretical Capacity, and Global Potential

cScience, Volume 2, Issue 2, June 2026.
ABSTRACT The construction sector constitutes a major source of global carbon dioxide emissions, and cement production contributes substantially via fuel combustion and limestone decomposition. These challenges have encouraged the incorporation of carbon dioxide into construction materials through mineralization.

Fluid‐Driven Cohesive Strengthening: Critical Role of Reaction Kinetics as the Determinant for Frictional Stability

AGU Advances, Volume 7, Issue 3, June 2026.
Abstract Following an earthquake, faults lock and regain strength via a combination of healing mechanisms that include pressure solution, contact growth, and cementation. Fault healing dictates strength recovery during the seismic cycle and is therefore a key factor controlling earthquake recurrence intervals, stress drop, and other source properties ...

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.

A Review of the Unintended Consequences of Biochar in Various Applications

Advanced Energy and Sustainability Research, Volume 7, Issue 5, May 2026.
Biochar is widely promoted as a sustainable material for applications ranging from soil amendment to energy storage and construction materials. This review critically examines the often‐overlooked and unintended consequences of biochar, including variability in properties, safety risks, and performance limitations.
