The use of cement and concrete, among the most widely used man-made materials, is under
scrutiny. Owing to their large-scale use, production of cement and concrete results in …

Blended cements, where Portland cement clinker is partially replaced by supplementary
cementitious materials (SCMs), provide the most feasible route for reducing carbon dioxide …

Carbonation hardening of Portland cement concrete can contribute to lower its CO 2
footprint and to improve its strength. The reaction mechanisms involved in carbonation …

Recycled concrete aggregate (RCA) differ from natural aggregate as the former contains
attached mortar. Given the recycling process of RCA, that is, by crushing, the microstructure …

Large volumes of carbon dioxide are released during mining and ore resource
development, and cemented paste backfill (CPB) materials are placed in the mined-out …

Recycled concrete aggregate differ from natural aggregate as the former contains hardened
cement mortar. The adhered cement mortar on recycled concrete aggregate has higher …

Cement paste is known to react with atmospheric carbon dioxide. Carbonation of cement
paste has long been recognized as one of the causes of reinforcement corrosion. On the …

Despite being considered as a potential carbon capture method, carbonation curing of
cement-based materials are still accompanied by serious concerns now. Strength loss and …

This article summarizes the existing knowledge regarding the carbonation of cement-based
materials and identified the areas which require further investigations. Available studies …

The accelerated carbonation technology has been utilized in order to enhance the
properties of the recycled concrete aggregates (RCAs) and efficient sequestration of carbon …
