For in situ reinforced concrete structures, carbonation has been considered as a risk that
needs to be inhibited for the past decades; while a pronounced carbonation in early age …

The paper studied the effect of pre-carbonation on the C–S–H structure and investigated the
positive effect of pre-carbonation on enhancing the stability of cement paste at high …

In this study, a low-carbon engineered cementitious composite (ECC) was produced by
combining alkali-activated red mud (RM)/ground granulated blast-furnace slag (GGBS) with …

Currently, there is a limited understanding of the material performance effects and hydration
mechanisms of solidified waste-based binder filling materials containing municipal solid …

When structural concrete is exposed to a fire, various changes in chemical and mechanical
properties proceed. The concentration of carbon dioxide CO 2 rises to about 15 …

Carbonation of calcium silicate (CS) minerals to produce hardened construction materials
has attracted increasing interest, but the efficiency of conventional CS minerals is low. This …

Steel slag, desulphurised ash, desulphurised gypsum and ultra-fine iron tailing sand are
common industrial solid wastes with low utilisation rates. Herein, industrial solid wastes …

The microstructural evolutions of both uncarbonated and carbonated cement pastes
subjected to various high temperatures (30° C, 200° C, 400° C, 500° C, 600° C, 720° C, and …

Concrete structures are exposed to various temperature environments and often come into
contact with CO 2 under these conditions. With the recent surge in interest in carbonation …

In this paper, MgO and silica fume (SF) are used to prepare MgO-SF cementitious materials,
physicochemical properties of MgO-SF materials at room temperature (RT), 100° C, 200° C …
