This paper aims to provide a systematical review of the available printing strategies,
sustainable cementitious materials and characterization methods for extrusion-based 3D …

The microstructural details of concrete and asphalt construction materials are crucial in
understanding and improving their material properties for structural applications in civil …

X-ray computed tomography (CT) is a non-destructive technique that offers a 3D insight into
the microstructure of thick (opaque) samples with virtually no preliminary sample …

Cement-based materials are generally highly heterogeneous, and their material properties
are strongly affected by the characteristics and spatial distributions of each constituent …

Progress in microstructural characterization methods is summarized. Special attention is
given to advanced probes, such as X-ray imaging and spectroscopy, 1 H NMR relaxometry …

This work is aimed at characterizing the effects of nanosilica (NS) on the properties of
lightweight aggregate concretes with different densities. Lightweight aggregate concrete …

For many 3D printed cementitious materials, air voids may play a dominant role in the
interlayer bond strength. However, to date, far too little attention has been paid to reveal the …

When cement-based materials are exposed to the high temperatures induced by fire, which
can rapidly cause temperatures of over 1000° C, the changes in pore structure and density …

Pore structure is a significant microstructural characteristic in cement-based materials and
dominates the mechanical and transport properties of the materials. In this study, sectional …

The inherent inferior quality of recycled coarse aggregate (RCA) influences the
microstructural characteristics and consequently, the macro-mechanical properties of …
