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.

Mechanistic insights into the anion‐driven suppression of the initial cement reaction of tricalcium aluminate

open access: yesJournal of the American Ceramic Society, Volume 109, Issue 1, January 2026.
Abstract The hydration process of ordinary Portland cement (OPC) involves intricate interactions among ions in the pore solution, dissolving clinker phases, and precipitating hydrates. Tricalcium aluminate (C3A${\rm C}_3{\rm A}$) shows the highest reactivity of the cement clinker phases during the initial hydration stages of OPC. The kinetic control of

Solidification/stabilisation of soil contaminated with metal: a review [PDF]

open access: yes, 2008
Solidification/stabilisation (S/S) is generically defined as a chemical and physical alteration technique of reducing the mobility as well as solubility of contaminants in wastes in order to convert them into chemically inert form.

Effects of a novel calcium aluminate cement on the early events of the progression of osteogenic cell cultures [PDF]

open access: yes, 2011
The present study evaluated the progression of osteogenic cell cultures exposed to a novel calcium aluminate cement (CAC+) in comparison with the gold standard mineral trioxide aggregate (MTA). Cells were enzimatically isolated from newborn rat calvarial

Influences of Aluminum Ash Slag on Mechanical and Microstructural Characteristics of Stabilized/Solidified Heavy Metal Contaminated Soils

open access: yesAdvances in Civil Engineering, Volume 2026, Issue 1, 2026.
Solidification/stabilization (S/S) is a widely adopted remediation technique for contaminated soils. However, how to efficiently and economically modify contaminated soil remains challenging. In this study, secondary aluminum ash slag (AAS) was employed as a novel stabilizer for the S/S treatment of lead (Pb) and zinc (Zn) contaminated soils.

Predicting the Compressive Strength of Ash‐Based Concrete Using Machine Learning Approach: Paving the Way to Sustainable Concrete

open access: yesAdvances in Civil Engineering, Volume 2026, Issue 1, 2026.
Industrial wastes, agricultural byproducts, and rock dust are considered suitable replacements for cement in eco‐friendly concrete production due to their comparable chemical properties. This study evaluates 13 ash sources as potential cement alternatives, explores machine learning (ML) algorithms to predict compressive strength (fc′) of ash‐blended ...

Potential of Saudi Arabian bauxite to produce low-carbon cement

open access: yesCement
To produce calcium aluminate cement (CAC), bauxites are usually fused with lime/limestone at high temperature (1600 °C). At this temperature, the bauxite´s hydrates of alumina break down - dehydroxylation - and combine with calcium forming monocalcium ...

Low‐Carbon Recycling of Engineering Muck Through Phosphogypsum: Modeling, Optimization, and Durability Performance Investigation

open access: yesAdvances in Civil Engineering, Volume 2026, Issue 1, 2026.
With the rapid development of urban infrastructure in China, engineering muck has emerged as a potential urban risk. The improper disposal of engineering muck not only results in the inefficient occupation of land resources but also poses serious threats to ecological systems and geotechnical stability.

Early-age monitoring of fresh cementitious material by acoustic emission [PDF]

open access: yes, 2017
Concrete properties are mainly affected by the fresh state since it has a significant impact on the long-term concrete performance. In this study, acoustic emission (AE) was applied to monitor the behavior of fresh cement paste.
