Effect of Graphene Nanoplatelet on the Carbonation Depth of Concrete under Changing Climate Conditions

Applied Sciences, 2021
Climate change has been unprecedented in the past decades or even thousands of years, which has had an adverse impact on the mechanical properties of concrete structures. Many researchers have begun to study new concrete materials. Graphene nanoplatelet (

The role of relative humidity and cement type on carbonation resistance of concrete

Alexandria Engineering Journal, 2019
Carbonation of concrete is one of the key factors causing deterioration for reinforced concrete structures. Carbonation depth is typically used to estimate the concrete service life.

A Cenozoic record of the equatorial Pacific carbonate compensation depth [PDF]

Nature, 2012
Atmospheric carbon dioxide concentrations and climate are regulated on geological timescales by the balance between carbon input from volcanic and metamorphic outgassing and its removal by weathering feedbacks; these feedbacks involve the erosion of silicate rocks and organic-carbon-bearing rocks.

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 ...

In-Depth Computational Analysis of Natural and Artificial Carbon Fixation Pathways [PDF]

BioDesign Research, 2021
Abstract In the recent years, engineering new-to-nature CO2 and C1 fixing metabolic pathways made a leap forward. These new, artificial pathways promise higher yields and activity than natural ones like the Calvin-Benson-Bassham cycle. The question remains how to best predict their in vivo
