The CSH gel is an elusive material. Its variable composition and disordered nature
complicate a complete characterization of its atomic structure, and the elaboration of models …

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

Calcium silicate aluminate hydrate (C (-A)-SH) is the main hydration product used in cement-
based materials. It plays a specific role in both the mechanical properties and volumetric …

This paper studied the influence of carbon nanotube (CNT) and graphite nanoplatelet (GNP)
used at 0 to 0.3%, by mass of binder, on composition, structure, and nano-mechanical …

Optimising the hydration of cementitious materials is crucial to leverage their full potential
and avoid wasting resources, embodied energy and CO 2. Understanding the fundamental …

This paper investigates how the composition of Portland composite cements affects their
chloride-binding properties. Hydrated cement pastes prepared with a reference Portland …

Abstract Systems of different Ca/Si and Al/Si molar ratios were investigated. Incorporation of
Al increases main basal spacing, amount of bounded water and decreases crystallinity of C …

Na 2 SO 4 activated slag (NSAS) is accepted as one of the most promising low carbon
cementitious materials, while its slow strength development seemed the most prominent …

Stoichiometrically-controlled alkali-activated pastes containing calcium-(sodium)
aluminosilicate hydrate (C-(N)-ASH) and sodium aluminosilicate hydrate (NASH) gels are …

Understanding the crystallization of cement-binding phases, from basic units to macroscopic
structures, can enhance cement performance, reduce clinker use, and lower CO2 emissions …
