Many alkali-activated materials (AAMs) exhibit poor workability in mixing owing to great
viscosity of the paste and fast setting. Chemical admixtures commonly used in Portland …

Geopolymers have been considered as a promising alternative to cementitious materials for
3D printing to enhance sustainability of the construction industry. This paper presents a …

Polycarboxylate (PC) superplasticizers are being widely used in concrete mixtures due to
their high water reduction rate and good slump retention at low dosage. The chemical …

Hybrid materials based on layered double hydroxides (LDHs) exhibit great potential in
diverse fields such as health care, polymer composites, environment, catalysis, and energy …

Adsorption of polycarboxylateether-based water-reducing admixtures (PCE) on the cement
surface affects many properties of cementitious systems, especially fluidity. One of the most …

Comparative study of NSF and PCE superplasticizers was carried out aiming at correlating
the adsorption in fresh cement pastes (fcps) with their dispersing capability and the impacts …

The traditional polycarboxylate (PC) superplasticizers are usually negatively charged
polymers, in which the carboxylate functionalities are responsible for their adsorption on …

This paper provides an overview of the use of nanoclays in cement-based materials. The
effect of nanoclays on shear rheological properties will be discussed, with a focus on …

The early hydration of alite, in particular the reason for the onset of the induction period, has
been a subject of controversy for many decades. Several theories have been proposed …

Linear models are commonly used to describe the early structural build-up of cement-based
materials. However, some studies have shown that there exists a faster non-linear phase …
