2009-2-1 Concrete repair by replacing cover concrete with an inert material against chloride-induced corrosion is considered. In order to study the durability and service life of repaired concrete structures, a quantitative assessment of chloride transport in repaired concrete structures is preferable.

2012-2-18 The service life of concrete structures is commonly modelled as a two stage process, defined respectively as the “initiation” and the “propagation” stage (see Figure 1.) Many studies have already been performed based on these processes over the last decades. Physical modelling is possible by reasonable approximation, although some aspects are still under debate. The limit state functions

2013-1-1 Thus, unlike normal (unrepaired) concrete structure, service life of repaired concrete structure depends on the quality of the composite system formed by the repair material and the existing concrete substrate as well as on the proficiency with which the repair works were carried out.

2020-10-13 Repairs are an inevitable and indispensable necessity. Given that conservation rules are observed,repairs are also used to save monuments, but first and foremost they help to restore or maintain theusability of existing structures. Consequently, repairs restore or extend expected durability. Due to thefact, that stone/brick skeletons have a much longer tradition in construction than that of Portland cementconcrete, the historical approach to structural repairs is also much deeper for masonry structures.In this context, it is worth recalling the very significant history of St. Peter’s dome repairs.In 1742, after two centuries after its completion, the masonry

Following this, practices for typical near-surface repair, corrosion protection, structural strengthening, structural stabilization, etc. will be discussed in detail. At the end of the course students will be able to suggest evaluation and repair/retrofitting methods for extending the service life of concrete structures.

2020-7-23 For the most part, concrete crack repair service utilizes polyurethane injection or epoxy injection. The common mistake that most people make is trying to fix the cracks using crack fillers without first evaluating the extent of the concrete damage. Most of the time, when you apply a quick-fix solution to a concrete

2013-1-1 The need to mitigate premature failure of repaired concrete structure had motivated some researchers to develop service life prediction model for repaired concrete structure, however, to the author’s knowledge, yet there are very few service life prediction models for repaired concrete structure, e.g. [36], [38].
