This book promulgates Natural Carbonation Prediction (NCP) model comprising experiments, data mining and analyses, along with mathematical formulations and refinements aimed at developing quantitative engineering methods, to address carbonation and corrosion issues in reinforced concrete structures.
Carbonation and corrosion of reinforced concrete structures is the most widespread durability problem affecting service life and it underscores the need to develop quantitative engineering methods. This book promulgates Natural Carbonation Prediction (NCP) model comprising experiments, data mining and analyses, along with mathematical formulations and refinements. It initially delves into fundamental concepts on corrosion of reinforced concrete before employing approaches to service life design based on the applicative and practical stochastic methods supported by independent data.
Features:
- Focusses on corrosion due to carbonation of Portland cement-based concrete.
- Covers natural carbonation mechanisms, and probabilistic service life design through reliability analysis and Monte Carlo simulation.
- Presents model for predictive approach for carbonation rate using a mathematical framework that incorporates key parameters for consideration in the design process.
- Using data from worldwide sources, various case studies from different countries globally, are employed comparing measurements with carbonation predictions.
- Delves into carbonation modelling, originating from theoretical underpinnings based on Ficks laws of diffusion.
This book is aimed at graduate students and researchers in civil engineering and concrete technology.
