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 …

It has been long recognized that low air pressure (AP) affects the moisture transfer in
concrete, and thus its microstructure and bulk property, but less is known about the …

Limestone calcined clay cement (LC3) is a green binder with great practical importance for
the cement industry. Growing application has increased the need to understand the …

In this study, the structure of synthetic magnesium silicate hydrated phases (MSH) and the
distribution of water as a function of the Mg/Si ratio were investigated. Different analytical …

The strength origin of CSH matrix is a key question in cement and concrete research, which
remains largely unclear despite a century of study. Here we present a novel approach to …

The specific surface areas of sealed-cured hardened cement pastes (HCP) were evaluated
during the hydration process using three types of Portland cement and with two different …

Cemented paste backfill (CPB) comprising mineral tailings, binders and mixing water is an
important potential support material in the mining industry. As the mechanical properties of …

Drying shrinkage of cement pastes (CPs) facilitating superficial cracking deserves primary
concern when evaluating durability performance. To clarify shrinkage mechanism, the …

In this study, the low-field nuclear magnetic resonance (NMR) testing technique was
adopted to experimentally investigate the seepage processes of chemical grout flow in …
