Residual Life of Corroding Reinforced Concrete Structures in Marine Environment
TL;DR: In this paper, an empirical relationship between the residual load capacity of a reinforced concrete element and the degree of reinforcement radius loss by corrosion was estimated, and a second empirical relationship was established based on available experimental data, which may be applicable to the performance of corroding prestressed-concrete elements.

Reinforcement corrosion initiation and activation times in concrete structures exposed to severe marine environments
Robert E. Melchers,Chun-Qing Li +1 more
TL;DR: In this paper, the authors present a systematic overview of cases reported in the engineering and corrosion literature and consider possible reasons for these differences, showing that concretes made from blast furnace cements have better corrosion durability properties.

Effects of two Danish flyashes on alkali contents of pore solutions of cement-flyash pastes
TL;DR: In this paper, the influence of flyash on the alkali contents and other characteristics of cement paste pore solutions was investigated by preparing pastes with 30 percent replacement of cement with flyash, hydrating for up to six months, and expressing and analyzing the resulting pore solution.

Diffusion of chloride and hydroxyl ions in cementitious materials exposed to a saline environment
G. Sergi,S. W. Yu,C. L. Page +2 more
TL;DR: In this paper, the free hydroxyl, free chloride and total chloride concentration profiles were determined after 100 days of exposure by analysis of the paste at various depths from the exposed surface.
