The Performance of Carbonation-Cured Concrete
Materials, 2019 The research shows that carbonation-cured concrete has several mechanical and durability properties that are better than those of moisture-cured concrete. However, many properties of carbonation-cured concrete have not yet been studied. In this research, carbonation-cured concrete was prepared by pre-curing, carbonation curing, and then moisture curing.

ENSURING CARBONIZATION RESISTANCE OF AUTOCLAVE HARDENED CONCRETE CONCRETE [PDF]
Modern technology, materials and design in construction, 2021 The analysis of tendencies of production of autoclaved aerated concrete is resulted. Given the price factor, energy and environmental status of the industry of construction wall and insulation materials, autoclaved aerated concrete has significant advantages over traditional wall materials and prospects for production.

Effect of autogenous healing of narrow and wide cracks on the progression of carbonation in the walls of cracks [PDF]
MATEC Web of Conferences, 2023 This paper deals with the carbonation of concrete crack walls before and after healing in comparison to the carbonation of the bulk of the concrete. Natural carbonation tests were carried out on 50 MPa concrete.

MODELLING THE CARBONATED CONCRETE REALKALIZATION
JOURNAL OF CIVIL ENGINEERING AND MANAGEMENT, 2009 The presented model of carbonated concrete realkalization is compiled on the basis of the multi‐component medium theory equations. The process equations have been obtained from an analysis of the partial equations of mass, electric charge, momentum, energy, and entropy inequality.

Microstructural examination of carbonated 3D‐printed concrete [PDF]
Journal of Microscopy, 2022 AbstractThe recent interest in 3D printing with concrete has generated great interest on how inhomogeneities arise and affect performance parameters, in particular strength and durability. With respect to durability, of particular interest is how 3D‐printed layer interfaces can impact transport of species of interest, such as moisture, chlorides or ...

Influence of Wind Pressure on the Carbonation of Concrete [PDF]
Materials, 2015 Carbonation is one of the major deteriorations that accelerate steel corrosion in reinforced concrete structures. Many mathematical/numerical models of the carbonation process, primarily diffusion-reaction models, have been established to predict the carbonation depth.

Analysis of Carbonation Behavior of Cracked Concrete
Materials, 2022 The crack and carbonation of concrete pose a great challenge to its durability. Therefore, this paper studies the effect of cracks on the carbonation depth of cement paste under different factors. The relationship between carbonation and cracks was determined, and the carbonation mechanism of cement paste with cracks was clarified.
