Numerical Estimation of Moisture Penetration Depth in Concrete Exposed to Rain—Towards the Rationalization of Guidelines for Durable Design of Reinforced Concrete in Tropics

摘要: Moisture imbibed within the porous matrix of concrete during course service plays a critical role in causing its degradation. Under tropical climatic conditions structural elements often get exposed to spells rainfall which result conspicuous ingress moisture and subsequently amenable for corrosion embedded steel reinforcement—the most prevalent cause premature durability failure reinforced (RC) elements. The estimation associated penetration depth is thus pivotal delineating near surface zone RC element remains susceptible damage. Such an estimate also enables ascertaining rationally cover be provided intended serve under otherwise adopted as per prescriptive standards currently vogue. present work numerically investigates aspect considering probable extremes scenarios pertaining composite climate New Delhi (India). exposure traits have been ascertained by statistically analyzing 15 years’ data obtained from archives Indian Meteorological Department. transport phenomenon has represented using modified form Richards’ equation constituted dimensionless terms achieve computational efficiency. material properties inputs analysis published experimental literature.
