Accelerated carbonation test data for concretes with varying slag content(Zenodo). [PDF]

Data in Brief
This paper presents a dataset of accelerated carbonation test results for 48 concrete mixes with varying binder compositions, water-to-binder ratios, and air-entrainment levels. The dataset includes raw and processed data on material properties, exposure

Behaviour of supersulfated cements under accelerated and natural carbonation [PDF]

MATEC Web of Conferences
It is known that supersulfated cement (SSC) is susceptible to carbonation; however, there are uncertainties regarding the similarity between accelerated and natural carbonation processes.

Performance of GGBS Cement Concrete under Natural Carbonation and Accelerated Carbonation Exposure

Journal of Engineering, 2021
One of the primary problems related to reinforced concrete structures is carbonation of concrete. In many cases, depth of carbonation on reinforced concrete structures is used to evaluate concrete service life.

Accelerated carbonation of hazardous wastes [PDF]

, 2011
Accelerated carbonation involves exposing a material to a concentrated atmosphere of carbon dioxide, and can be used to treat hazardous wastes and soils and create new construction materials. The present work examines the use of accelerated carbonation to reduce the hazardous properties of wastes as a means of reducing the costs of disposal to landfill,

Novel accelerated carbonation methods based on deep breathing analogous and prediction model for pressurized carbonation of concrete [PDF]

Scientific Reports
This research proposes a novel deep breathing analogy (DBA) accelerated carbonation process. Inspired by the breathing mechanism of human lungs, the DBA method involves injecting pure CO2 into a reaction chamber at a specific pressure (inspiration) and ...

Homogeneous catalysis of the accelerated carbonation of Portland cement [PDF]

, 2013
A mechanism proposed for the accelerated carbonation of Portland cement has shown how the reaction proceeds through gaseous, liquid and solid phases in 9 distinct sequential steps. The overall speed of reaction is thus determined by the slowest step, and

Limit values of accelerated carbonation resistance to meet EC2 durability requirements [PDF]

Građevinski Materijali i Konstrukcije, 2022
Although accelerated carbonation resistance has been extensively tested, there are no recommendations for the application of test results in codes of practice.

Carbonation Behavior of Engineered Cementitious Composites under Coupled Sustained Flexural Load and Accelerated Carbonation. [PDF]

Materials (Basel), 2022
Engineered cementitious composites (ECCs) belong to a broad class of fibre-reinforced concrete. They incorporate synthetic polyvinyl alcohol (PVA) fibres, cement, fly ash and fine aggregates, and are designed to have a tensile strain capacity typically ...

Agricultural acceleration of soil carbonate weathering [PDF]

Global Change Biology, 2020
AbstractSoil carbonates (i.e., soil inorganic carbon or SIC) represent more than a quarter of the terrestrial carbon pool and are often considered to be relatively stable, with fluxes significant only on geologic timescales. However, given the importance of climatic water balance on SIC accumulation, we tested the hypothesis that increased soil water ...

Permafrost collapse is accelerating carbon release [PDF]

Nature, 2019
The sudden collapse of thawing soils in the Arctic might double the warming from greenhouse gases released from tundra, warn Merritt R. Turetsky and colleagues.
