Cement is the ubiquitous material upon which modern civilisation is built, providing long-
term strength, impermeability and durability for housing and infrastructure. The fundamental …

X-ray computed tomography (CT) is a non-destructive technique that offers a 3D insight into
the microstructure of thick (opaque) samples with virtually no preliminary sample …

In this review, we discuss the recent advances in understanding ye'elimite-rich cements.
These cements can be classified as follows:(1) Low belite ones namely called calcium …

Progress in microstructural characterization methods is summarized. Special attention is
given to advanced probes, such as X-ray imaging and spectroscopy, 1 H NMR relaxometry …

Despite a century of research, our understanding of cement dissolution and precipitation
processes at early ages is very limited. This is due to the lack of methods that can image …

Abstract Ye'elimite (Ca 4 Al 6 O 12 SO 4 or C 4 A 3 S¯) is the main hydraulic mineral present
in calcium sulfoaluminate cement (CSA). The hydration of ye'elimite is responsible for the …

This paper discusses the effect of alkalis on strength development and hydration products in
a commercial calcium sulfoaluminate clinker (KCSA). KCSA pastes were hydrated with …

Ye'elimite occurs in nature and in calcium sulfoaluminate cements. The thermodynamic
properties of synthetic orthorhombic ye'elimite, Ca 4 Al 6 O 12 SO 4, were determined …

There is still an ongoing debate on the mechanisms of expansion of calcium sulfoaluminate
(CSA) cements, which can be either favourable, for example, in shrinkage compensating …

This paper investigated the influence of hydration temperature on the nanostructure of the
AH 3 phase formed in calcium sulfoaluminate cements. Orthorhombic ye'elimite (st …
