Analytical Model and Data-driven Approach for Concrete Moisture Prediction
The advent of smart sensing technologies has opened up new avenues for addressing the billion dollar problem in the wastewater industry of H2S corrosion in concrete sewer pipes, where there is a growing interest in monitoring the environmental properties that govern the rate of corrosion. In this context, this paper proposes a methodology to predict the moisture content of concretes through dat...
متن کاملPrediction of Heat Transfer Coefficient for Thermal Regenerators
Correlation of heat transfer coefficients for air flow through the regenerator constructed from randomly paked spheres is reported for the symmetric-balanced mode of operation. The experimental results have been correlated by the least square regression has been obtained.The present correlation has been compared with the heat transfer coefficient correlations in the literature.
متن کاملHeat and Moisture Transfer through Clothing
The UC Berkeley Comfort Model is a helpful simulation tool for the assessment of thermal comfort in non-uniform environments. A major element of the model is the implementation of a clothing node, which considers both heat and moisture capacitance of clothing. Heat capacity of the clothing has been demonstrated to be important when considering transient effects. Moisture capacitance is importan...
متن کاملEvaluation of the Carbon Dioxide Uptake of Slag-Blended Concrete Structures, Considering the Effect of Carbonation
During the production of concrete, cement, water, aggregate, and chemical and mineral admixtures will be used, and a large amount of carbon dioxide will be emitted. Conversely, during the decades of service life of reinforced concrete structures, carbon dioxide in the environment can ingress into concrete and chemically react with carbonatable constitutes of hardened concrete, such as calcium h...
متن کاملTowards practical carbonation prediction and modelling for service life design of reinforced concrete structures
Amongst the scientific community, the interest on durability of concrete structures has been high for quite a long time of over 40 years. Of the various causes of degradation of concrete structures, corrosion is the most widespread durability problem and carbonation is one of the two causes of steel reinforcement corrosion. While much scientific understanding has been gained from the numerous c...
