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

open access: yescScience, 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.

Effect of silica fume additions on the hydration behaviour of calcium aluminates [PDF]

open access: yes, 1997
In the recent refractory castables technology, the calcium aluminate cement is being replaced in increasing proportion by very fine matrix components, such as silica fume and colloidal alumina.

Ag2O-Ag/CAC/SiO2 composite for visible light photocatalytic degradation of cumene hydroperoxide in water

open access: yesJournal of Materials Research and Technology, 2019
A visible light-active composite, Ag2O-Ag/CAC/SiO2, was produced by loading an aqueous silver salt solution onto the layer of hydrated calcium aluminate cement coating on porous SiO2 sphere. The mild cement hydration condition induced the formation of in

Influence of radiopacifier additives on calcium aluminate cement properties [PDF]

open access: yesMaterials Research, 2014
The aim of this study was to determine the best radiopaque additive to be incorporated to calcium aluminate cement (CAC) to promote radiopacity. Measurements of optical density were carried out on white MTA and CAC with and without additives such as ...

Clays for Low‐Carbon Cements: Overview, Progress, and Challenges

open access: yesGlobal Challenges, Volume 10, Issue 1, January 2026.
This review provides a critical overview of recent developments of activated clays to function as artificial pozzolans. After a thorough description of the clays that yield good pozzolanic performances, selected examples are given on thermal and mechanical activations. Chiefly, general correlations are extracted from reported data despite its scattered

The effects of cement type and expanded vermiculite powder on the thermo- mechanical characteristics and durability of lightweight mortars at high temperature and RSM modelling

open access: yesCase Studies in Construction Materials, 2021
The results of the impact of cement type and expanded vermiculite powder (EVP) on the thermal, mechanical characteristics and durability of lightweight mortars at high temperature and RSM modelling are presented in the paper. The lightweight mortars were

Microbial Deterioration Potential and Mitigation Strategies in Blended Cement Structures: A Review

open access: yesAdvances in Civil Engineering, Volume 2026, Issue 1, 2026.
Microbial‐induced deterioration (MID) is a threat to the durability of cement‐based materials (CBMs) particularly in sewer and wastewater systems. Whereas blended cements incorporating supplementary cementitious materials (SCMs) offer environmental benefits such as reduced carbon (IV) oxide (CO2) emissions and enhanced mechanical performance, their ...

Microstructure development in mixes of calcium aluminate cement with silica fume or fly ash

open access: yes, 2009
The most widely identified degradation process suffered by calcium aluminate cement (CAC) is the so-called conversion of hexagonal calcium aluminate hydrate to cubic form.

Investigation of the milling route for the development of colloidal suspensions to be used as binder in refractory castables

open access: yesOpen Ceramics, 2023
Refractories castables bonded with CAC (calcium aluminate cement) have a limitation when they are used at high temperature in micro-silica containing system and/or in acidic corrosive environments.
