Effect of Chloride Diffusion on Corrosion Behavior of 304SS Steel in Simulated Concrete Solution under Carbonation Condition

International Journal of Electrochemical Science, 2021
The corrosion behavior of 304 stainless steel reinforced concrete in the simulated seawater environment is studied using the ion diffusion method to accelerate the carbonation process of the simulated concrete stainless steel system.

MECHANISM OF CARBONATION AND PREDICTION OF CARBONATION PROCESS OF CONCRETE

Doboku Gakkai Ronbunshu, 1990
Accelerated carbonation test is performed to explain mechanism of carbonation of concrete. The depth of carbonation, the weight loss of mortar, the amount of calcium hydroxide and calcium carbonate, and pore volume and pore size distribution are measured. Water immersion test and air exposure test after accelerated carbonation test is also performed to

Hydration Behavior of Tricalcium Silicate in Seawater Relevant Salt Systems: A Hybrid Study with the Aid of Machine Learning

Advanced Intelligent Discovery, EarlyView.
The hydration behavior of C3S in seawater‐relevant solutions is studied based on experiments, boundary nucleation and growth (BNG) modeling, and machine learning. The main ions included in seawater modify hydration mechanisms, with MgCl2 showing the strongest acceleration effect at the same concentration.

Numerical Simulation on Carbonation Depth of Concrete Structures considering Time- and Temperature-Dependent Carbonation Process

Advances in Materials Science and Engineering, 2018
In order to further understand the carbonation process of concrete structures, the time- and temperature-dependent diffusion process of CO2 in concrete is simulated based on the law of the CO2 mass conservation, and a two-dimensional mass transfer ...

Prediction‐Guided Two‐Step Solid‐State Exploration of Unknown Pseudo‐Ternary Oxides

Advanced Intelligent Discovery, EarlyView.
Prediction‐guided selection combined with two‐step solid‐state exploration enables efficient search of unknown pseudo‐ternary oxides. Broad robotic slurry screening followed by manual single‐phase isolation leads to the discovery of a new oxide, Ba5SnV6O22, showing how data‐guided experiments connect unexplored composition regions to new materials ...

A reaction-diffusion modeling of carbonation process in self-compacting concrete

, 2015
© 2015 Techno-Press, Ltd. In this paper, a reaction-diffusion model of carbonation process in self-compacting concrete (SCC) was realized with a consideration of multi-field couplings. Various effects from environmental conditions, e.g.

AACM and Low Carbon Concrete

The Institute of Concrete Technology Yearbook: 2022-2023 27th Edition, 2022
This paper addresses some of the key drivers for, and barriers to, the broader uptake of alkali-activated cementitious materials as potentially lower-carbon binders for use in construction, with a particular focus on the UK industry and market. For a material to succeed in practice, it must be able to be produced at sufficient scale and acceptable cost,

The coelurosaur theropods of the Romualdo formation, early Cretaceous (Aptian) of Brazil: Santanaraptor placidus meets Mirischia asymmetrica

The Anatomical Record, EarlyView.
Abstract The upper carbonate concretion levels of the Romualdo Formation (Aptian, Brazil) have yielded several theropod dinosaur remains, including spinosaurids and the coelurosaurs Santanaraptor placidus and Mirischia asymmetrica, the phylogenetic affinities of which are controversial.
