Simulate and predict NMR spectra directly from your webbrowser using standard HTML5. You can also simulate 13C, 1H as well as 2D spectra like COSY, HSQC, HMBC. Second order effect like AB, ABX, AA'XX' can be simulated as well.
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...
30 cze 2020 · Non-destructive testing methods for practical carbonation prediction are desirable. Abstract. Carbonation of cementitious materials can greatly shorten the length of lifetime for steel-reinforced concrete structures constructed in atmospheric environment, due to steel corrosion issue.
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.
11 mar 1990 · NMR can be utilized to study the degree of hydration, the reactivity of pozzolanic materials, clinker composition, interaction of organic admixtures with cement minerals, the different states of water in concrete, etc.
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.
22 gru 2022 · Predicting carbonation resistance via early site tests is crucial for controlling the longevity and durability of concrete structures. Therefore, this study aimed to provide a nondestructive approach for predicting carbonation resistance utilizing in situ air-permeability and surface moisture measurements. The Torrent air-permeability method, ...
