Viscosity modifying agents (VMAs) are essential ingredients for the production of flowable
cement-based materials. This paper presents an overview of commonly used VMAs and …

Abstract 3D printing technology (3DP) has provided new design and structural opportunities
for cement-based systems (CBS) in architectural construction. However, there are still some …

Magnesium oxide (MgO), which develops physical strength through carbonation, is a
potential alternative to carbon intensive Portland cement. In this paper, we examined …

In this study, a highly flowable, rapid set crack repair grout powder (CRG) was used to
facilitate mix design of 3D printing mortar. Various mortar mixtures with different amounts of …

Most of the experiments on additively manufactured polymers are on a small scale, and it
remains uncertain whether findings at a small scale can be extrapolated to their larger-scale …

Solid-like behaviors of fresh cement pastes are gaining increased attention with the
emergence of 3D concrete printing. It is known that the fresh cement paste exhibits a “two …

Nanoclays, nanosilica and viscosity modifying admixtures can be used to tune rheological
properties of cement pastes, in order to fulfill the requirements for non-conventional cast-in …

A concrete system is identified as highly printable if it can offer minimal resistance to
handling while sustaining high load resistance and structural stability. One of the major …

It is common to perform small-scale prototyping before large-scale application of three-
dimensional (3D) printing technology and in this case size effects can have an important …

Self-compacting concrete (SCC) is an energy efficient building technology widely used for
multiple constructive applications. However, the large flowability of fresh SCC produces an …
