Effects of CaO-based expansive agent on carbonation resistance of marine concrete

Case Studies in Construction Materials
Marine concrete contains a high volume of supplementary cementitious materials, which benefits low-carbon concrete production. However, they may also increase the risk of cracking and accelerate the carbonation due to the pozzolanic reaction ...

Preliminary study of the effect of carbonation curing on geopolymers

Revista IBRACON de Estruturas e Materiais, 2023
Carbonation curing differs from weathering carbonation since it is performed intentionally at the early ages of cement hydration. This cure involves applying different levels of CO2 (5% to 99%) to concrete for a short period of time, usually followed by ...

Optimal Mixture Design of Low-CO2 High-Volume Slag Concrete Considering Climate Change and CO2 Uptake

International Journal of Concrete Structures and Materials, 2019
High-volume slag (HVS) can reduce the CO2 emissions of concrete, but increase the carbonation depth of concrete. In particular, because of the effects of climate change, carbonation will accelerate.
