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 ...

Assessment of Pozzolanic Activity Using Methods Based on the Measurement of Electrical Conductivity of Suspensions of Portland Cement and Pozzolan [PDF]

Materials, 2014
The use of methods based on measuring electrical conductivity to assess pozzolanic activity has recently been used primarily in aqueous suspensions of pozzolan: calcium hydroxide. However, the use of similar methods in suspensions of cement with pozzolans has not been widely studied.

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.
