26 mar 2024 · Wu et al. developed a prediction model using the RF algorithm, established training and testing sets based on raw data, and successfully predicted concrete carbonation depth. Similarly, Londhe et al. [ 87 ] employed Model Tree, RF, and MGGP methods to predict the carbonation coefficient of concrete.
30 cze 2020 · Effects of environmental conditions (temperature, humidity, and CO 2 concentration), external factor of mortar surface coating, and internal factor of concrete compressive strength on natural carbonation process were evaluated and considered in the modified mathematical model for prediction of carbonation depth in existing concrete structures ...
3 wrz 2024 · The RILEM TC 281-CCC ‘ Carbonation of Concrete with Supplementary Cementitious Materials ’ has conducted a critical analysis of the standardised testing methodologies that are currently applied to determine carbonation resistance of concrete in different regions.
1 kwi 2020 · The results of a coupled chemo-mechanical test with an injection of CO2-saturated water display that the CO2 flow rate in the cement rapidly decreases, finally resulting in carbonation clogging of the cement sample. They seem consistent with reported field observations.
25 maj 2024 · Introduction. Exposure to aggressive environments can widely affect the safety and durability of reinforced concrete structures (RCSs). One of the main deterioration mechanisms affecting the...
depth carbonation of concrete samples with dierent water to cement ratios under dierent time were tested by the ve methods. A comparison on the determination procedures and data from the...
16 lut 2023 · With the aim of evaluating the effects of different possible carbonation reactions on the characteristics of reinforced concrete and preventing the potential harmful of the carbonation process, the carbonation degree must be quantified and predicted.
