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

The bulk of the cement industry's environmental burden is from the calcareous source.
Calcium is mostly available naturally as limestone (CaCO 3), where almost half of the mass …

Thermodynamic modelling can reliably predict hydrated cement phase assemblages and
chemical compositions, including their interactions with prevailing service environments …

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 …

Geopolymer (GP) binders are an appealing alternative to Portland cement (PC) binders as
they have the potential to reduce the CO 2 emissions associated with the cement and …

Supplementary cementitious materials (SCM) are increasingly used in concrete for
economical and environmental reasons. However, the durability of reinforced concretes …

The cement industry is a major industrial producer of greenhouse gases, responsible for 5–
8% of man-made CO 2 emissions. The carbonation reaction, which occurs between CO 2 …

The effects of two different low calcium fly ashes on the hydration of ordinary Portland
cement (OPC) pastes containing 50wt.% of fly ash were investigated over a hydration time of …

Thermodynamic modelling is essential to understand the effect of binder composition on
hydrate assemblage in modern Portland composite cements and its effect on durability …

Factors which could explain the slowing down of the metakaolin reaction in LC 3 blends are
investigated. Portlandite availability and the presence of aluminium ions in the pore solution …
