This paper explores the sustainability aspects of binders used in concrete 3D concrete
printing. Firstly, a prospective approach to conduct sustainability-assessment based on the …

Several million cubic meters of concrete are pumped daily, as this technique permits fast
concrete placement. Fundamental research has been performed and practical guidelines …

This study investigates the effect of the alkali-free aluminium sulphate based accelerator on
the printability and buildability of 3D printable concrete. The accelerator is introduced at …

The performance of various new biopolymers as viscosity-modifying admixtures (VMAs),
including tragacanth, almond, and locust bean gums and giant kelp extract, in addition to …

Bleeding, a type of static segregation derives from density difference of concrete ingredients
in fresh state. Due to having this difference higher than normal weight counterparts …

The study aims at understanding the criticality of interaction between the binder matrix and
aggregate when a 3D printable mix is subjected to compression at an early age. Two binder …

The accepted methods for testing concrete are not favorable for determining its
heterogeneity. The interpretation of the compressive strength result as a product of …

Pumping of self-consolidating concrete (SCC) is a vital construction technique. Curiosities
are aroused by the effect of this intense physical process on the hardened properties of …

Cellulose-ether-based viscosity-modifying admixtures (VMAs), such as methyl hydroxyethyl
cellulose (MHEC), are commonly used for improving the printability of 3D printed concrete …

Successful implementation of extrusion-based three-dimensional (3-D) printing requires the
development of print materials with adapted rheology. In this study, filtration characteristics …
