Reinforcement – Contamination and rust
The strength and performance of reinforced concrete depend on a good bond between the steel and the concrete It is only possible to achieve this if the steel is in good condition All reinforcement should be protected from contamination by grease, oil, mud, mould oil, excessive rust (especially if it is flaky) and ice, plus any mill scale or concrete that is looseAssessment of corrosion protection methods for reinforced concrete Ana María AguirreGuerrero, Ruby Mejía de Gutiérrez, in EcoEfficient Repair and Rehabilitation of Concrete Infrastructures, 2018 131 Introduction In recent decades, reinforced concrete has been one of the most used materials in the construction sector, especially in the construction of bridges, buildings, Reinforced Concrete an overview ScienceDirect TopicsThe term fibrereinforced concrete is defined by ACI 116R, Cement and Concrete Terminology, as a concrete containing dispersed randomly oriented fibres (Figure 181) [3]Fibre reinforced concrete can be described as a composite material consisting of a concrete phase and a small portion of discrete and discontinuous fibres distributed and oriented randomly within the Fiber Reinforced Concrete an overview ScienceDirect TopicsThe steel–concrete interface (SCI) is a complex, multiphase and multiscale system It is widely known to influence the performance and longterm durability of concrete structures However, a fundamental understanding of its properties and effects on corrosion initiation of embedded reinforcing steel remains elusive This is attributed to its complicated heterogeneity and time Methods for characterising the steel–concrete interface to
