Enhancement of the pozzolanic activity of natural clays by mechanochemical activation

Construction and Building Materials, 2022
Replacement of cement with supplementary cementitious materials (SCMs) is a proven method to reduce clinker in cement and contribute to decreased CO2 emissions. Natural clays are commonly occurring materials that do not possess pozzolanic activity in their original state.

Efficiency of Superplasticizers in Low‐carbon Alkali‐activated Slag–Silica Fume Binders Governed by Polymer Solubility

Journal of the American Ceramic Society, Volume 109, Issue 8, August 2026.
ABSTRACT Workability control of alkali‐activated binders (AABs) remains an obstacle to producing low‐carbon clinkerless ultra‐high‐performance concrete, as their formulation usually necessitates low water‐to‐binder (W/B) ratios, high binder content, and concentrated activator solutions. To address this challenge, a greener and more manageable composite

Ettringite Seeds for Strength Enhancement: Novel Synthesis via One‐Step Co‐Precipitation

Journal of the American Ceramic Society, Volume 109, Issue 8, August 2026.
ABSTRACT Reduced early strength can be a barrier to the adoption of cements blended with high levels of limestone. Chemical admixtures based on nucleation seeding are emerging as a potential solution. Herein, while synthesis of C‐S‐H‐based seeds has been thoroughly investigated in the literature, there are limited synthesis protocols available on other

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.

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 ...
