Research and Advances in the Application of Phosphogypsum in Pavement Base Course and Subgrade: A Review

Applied Research, Volume 5, Issue 5, October 2026.
This review highlights how pretreatment and optimized mixture design enable the use of phosphogypsum in pavement base courses and subgrades. Combining physical, chemical, or thermal treatment with suitable binders and solid wastes can improve engineering performance, durability, and environmental safety.

EVALUATION OF POZZOLANIC REACTIVITY OF CALCINED KAOLINITE

International Journal of Research in Engineering and Technology, 2014
The need to improve the sustainability and the need for innovation in the cement industry has brought to light the practice of using additives to the cement in order to decrease CO2 emissions in industrial plants and increase the quality of cement in terms of durability and performance.

Laboratory vs. pilot scale calcination of illitic and smectitic clays

ce/papers, Volume 9, Issue 6, Page 280-293, October 2026.
Abstract One strategy to reduce the carbon footprint of concrete is the partial substitution of cement clinker with supplementary cementitious materials (SCMs). In particular, clays have a potential to fulfil this role, as they are globally abundant and can be activated using simple methods.

Leached spodumene concentrate as SCM for cementitious applications

ce/papers, Volume 9, Issue 6, Page 294-302, October 2026.
Abstract Leached spodumene concentrate (LSC) was tested for cementitious applications as SCM. It was characterized by XRF, ICP‐OES and XRD. SEM was applied for microstructure analysis. Tests with prepared mixtures of LSC and OPC for cement applications considered the pozzolanic activity and the compressive strength.

Reactivity Assessment of Pozzolanic Materials for Partial Replacement of Cement in Concrete

, 2023
Reductions in portland cement use have important benefits in reducing the embodied energy in concrete and controlling CO2 emissions. Developing new, sustainable, and low-carbon construction materials is critical in addressing climate change.

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

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

Mechanochemical activation of phyllosilicates: Residual hydroxyl groups and their impact on surface properties and pozzolanic reactivity

ce/papers, Volume 9, Issue 6, Page 372-380, October 2026.
Abstract Mechanochemically activated (MCA) phyllosilicates are promising supplementary cementitious materials (SCMs) due to their pozzolanic reactivity and CO2 reduction potential. MCA of 2:1 and 2:1:1 phyllosilicates can induce significantly higher reactivity than thermal activation (TA). Unlike TA, which removes hydroxyl groups, MCA partially retains

Comparative Assessment of Calcined and Mechanically Activated Muscovite Clay as Supplementary Cementitious Material

ce/papers, Volume 9, Issue 6, Page 459-468, October 2026.
Abstract This study evaluates activated a high‐grade muscovite clay as a Supplementary Cementitious Material (SCM). This sample is an archetype to understand the behaviour of muscovite‐containing clays. The high‐grade clay was: (i) thermally activated (CMs) and (ii) mechanochemically activated (MMs).
