Mechanistic insight into mineral carbonation and utilization in cement-based materials at solid–liquid interfaces

Abstract

Synchrotron-based X-ray analyses for understanding the reactions at mineral–water interfaces for CO2 mineralization and utilization using petroleum coke fly ash.

Data‐Driven Analysis of Amine‐Based Sorbents for CO2 Removal from the Atmosphere

“…Their low selectivity towards CO 2 , due to physisorption of water, oxygen, and nitrogen, is however their main drawback, especially when highpurity CO 2 is needed for a downstream process such as sequestration [13,14]. While alkaline metal-based sorbents are highly selective towards CO 2 , they suffer from higher regeneration energy requirements as well as high mass transfer resistance towards CO 2 capture when the surfaces of their grains are passivated through CO 2 capture [11,15]. Metal organic frameworks (MOFs) are found to be highly active in CO 2 adsorption [13,16,17].…”

Tracing carbonation in cementitious slurry using anthocyanin extracted from fresh or stale petals

“…From the perspective of achieving carbon neutralization, tracing carbonation also seems indispensable. By promoting engineering technologies such as concrete waste carbonation, 11 carbonation curing, 12 etc., the concrete-related CO 2 emission can be signicantly reduced, and the "role" of cement industry may thus change from the largest CO 2 emitter to the largest carbon sink. [12][13][14] Therefore, for the purpose of carbon sequestration in cement industry, tracing carbonation is also essential, as it can help tune the engineering techniques associated with carbon sequestration.…”

By promoting engineering technologies such as concrete waste carbonation, 11 carbonation curing, 12 etc. , the concrete-related CO 2 emission can be significantly reduced, and the “role” of cement industry may thus change from the largest CO 2 emitter to the largest carbon sink.…”

Evolution of C–S–H in lime mortars with nanoparticles: Nanostructural analysis of afwillite growth mechanisms by HRTEM

“…[39][40][41][42] Afwillite (Ca 3 Si 2 O 7 ⋅3H 2 O), amongst the C-S-Hs, plays a significant role in the hydration process of cement pastes and concrete, 43,44 prompting microstructure modifications. 6,21,22,45 For this reason, there is an interest in synthesizing afwillite to accelerate the hydration process. 22,[46][47][48] Nevertheless, there is no reported afwillite in lime mortars up to the present time.…”
