Modeling reaction-driven cracking during mineral carbonation
This model evaluates water and CO 2 flow through peridotite fractured at different scales using a multiple continuum mesh. The effect of fluid flow, chemical reactions, and porosity and permeability feedbacks on carbonation rate and extent are explored, as is the effect of temperature.
Carbonation in Water Model
This example shows how to model carbonation, which is a type of sparging. Sparging is a mass transfer process between a gas and a liquid that is common in industry (such as beverage carbonation and photobioreactor applications) and at home (aquarium aeration).
Numerical Simulation on Carbonation Depth of Concrete Structures considering Time- and Temperature-Dependent Carbonation
Abstract In order to further understand the carbonation process of concrete structures, the time- and temperature-dependent diffusion process of CO 2 in concrete is simulated based on the law of the CO 2 mass conservation, and a two-dimensional mass transfer equation is established for the CO 2 …

Carbonation Resistance Performance and Micro-Structure
NC had better carbonation resistance than GHBC, and GHBC had a carbonation depth of 1.61 times than that of NC at 28 days accelerated carbonation experiment. The microstructural analysis showed that with the decrease of porosity of the samples, the carbon content and CaCO3 content increased after carbonation.

Modelling lime mortar carbonation
The carbonation process in lime mortar is influenced by the diffusion of carbon dioxide into the mortar pore system, by the kinetics of the lime carbonation reaction, and by the drying and wetting process in the mortar. All these phenomena depend on the presence of water in the mortar. Water is present in liquid form as well as vapour. Physical models and their mathematical basis are given for ...
CARBONATION OF CONCRETE STRUCTURES
Carbonation of concrete is a process by which carbon dioxide from the air penetrates into concrete through pores and reacts with calcium hydroxide to form calcium carbonates. It has seen that the conversion of Ca(OH) 2 into CaCO 3 by the action of CO 2 results in a small shrinkage.
The Science of Carbonation: A Visual Guide to Great Carbonation
There is precise science behind great carbonation. Creating great carbonation is the starting point of wonderful sparkling beverages. It is easy to reduce carbonation levels, but the maximum carbonation possible is determined by the technology used to create it. In this post we share our three years of R&D to help you understand how to consistently create powerful carbonation. Powerful bubbles ...

The carbonation process can be quantitatively accessed by a parameter, which can be obtained by means of the electrochemical impedance spectroscopy (EIS)-based electrochemical model. It has been found that the parameter is a function of carbonation depth and of carbonation time. Thereby, prediction of carbonation depth can be achieved.
Confused About Carbonation? - Ask Dr. Weil
Soft drinks are bad for teeth, especially in children. But the carbonation isn’t to blame; it’s the high sugar content of these beverages that is responsible for tooth decay, which is now the most common childhood disease – five times more common than asthma, according to the American Dental Association.
