“…Carbon capture and storage at fossil fuel burning sites like power plants or steel plants is a more efficient process and thus less expensive than direct air capture (Hansen et al, 2017). Several authors (Jang et al, 2016) have studied the use of CO 2 as accelerated curing of cementitious constructions materials. This technology will in future prevent carbon dioxide to be released into the atmosphere but it will also accelerate curing and strength development of those materials.…”

Carbon dioxide sequestration is crucial for targets limiting global warming could be achieved. This paper discloses results of an investigation concerning the performance of fly ash/waste glass alkaline-based mortars with two additives and recycled aggregates exposed to accelerated carbon dioxide curing. Mechanical properties as well as water absorption, drying shrinkage and carbon sequestration potential were studied on it. The results show that the mixtures with calcium hydroxide and sodium hydroxide concentration of 8 M leads to the highest compressive strength (10 MPa) which is high enough for the production of masonry blocks. Significant correlations between the flexural strength and the compressive strength were noticed. The mixtures show a low water absorption by immersion (9%) as well as by capillary (1.4 kg/m 2 H 0.5). The results of the modulus of elasticity show that increasing the sodium hydroxide molarity increased the stiffness of the mixtures. The results of drying shrinkage are in line with the results of the capillary water absorption and of the elastic modulus. A maximum CO 2 sequestration (164 kgCO 2 eq/m 3) is noticed for the mixture with a sodium concentration of 8 M based on the additive calcium hydroxide. The mortars were made of fly ash (FA), calcium hydroxide (CH),

“…As a consequence it is important to study how CO 2 generated by power plants and other facilities can be sequestrated in valuable products. Several authors [10,17] have studied the use of CO 2 as accelerated curing of cementitious constructions materials. This technology will in future prevent carbon dioxide to be released into the atmosphere but also to accelerate curing and strength development of those materials.…”

“…Different solutions have been adopted to reduce the carbon footprint of the construction industry such as partial replacement of PC with waste materials [ 6 , 7 , 8 ], alternative clinkers [ 9 ], and the use of alkali-activated binders [ 10 , 11 , 12 , 13 ]. Recently, the carbonation curing of PC-based materials has become a focus of attention as a potential means of reducing the atmospheric CO 2 concentration [ 14 , 15 ].…”

The feasibility of carbonation curing of ternary blend Portland cement–metakaolin–limestone was investigated. Portland cement was substituted by the combination of metakaolin and limestone at levels of 15%, 30%, and 45% by the mass. The ternary blends were cured with four different combinations of ambient and carbonation curing. The mechanical property, CO2 uptake, and mineralogical variations of the ternary blend pastes were investigated by means of compressive strength test, thermogravimetric analysis, and X-ray diffractometry. In addition, volume of permeable voids and sorptivity of the ternary blends were also presented to provide a fundamental idea of the pore characteristics of the blends. The test results showed that the increasing amount of metakaolin and limestone enhanced the CO2 uptake, reaching 20.7% for the sample with a 45% cement replacement level at 27 d of carbonation. Meanwhile, the compressive strength of the samples was reduced up to 65% upon excessive incorporation of metakaolin and limestone. The samples with a replacement level of 15% exhibited a comparable strength and volume of permeable voids to those of the sample without substitution, proving that the ternary blend Portland cement–metakaolin–limestone can be a viable option toward the development of eco-friendly binders.
