Residual Engineering Properties of Corroded Conventional Steel, High Chromium Steel and Stainless Steel Reinforcing bars in Concrete
… in the engineering properties of corroded steel rebar. This work presents the findings of the experimental study of the effect of corrosion on the engineering properties of conventional and common resistant corrosion steel rebar that are commonly used in reinforced concrete structures. Sets …

Mechanical Properties of Polymer Modified Mortar
… an isopthalic polyester matrix material. The FRP rebar was compared to standard steel rebars, and found that the standard steel corrugated rebar had a higher adhesive strength, due to mechanical interlocking. This was clarified by measurements using a smooth steel rebar. Characterization of the …

Mitigation of early age cracking of concrete for bridge decks
… such as early age cracking cause the reinforcing steel rebar to be exposed prematurely to the elements of the environment, which causes for lower service life of the bridge deck through corrosion of the reinforcing steel in the bridge deck. In harsh environments, such as the Midwestern United …

A study of fiberglass-reinforced plastic for reinforcing concrete bridge decks
… of the damage can be attributed to corrosion of steel reinforcing bars. Numerous solutions have been suggested, one of which is the replacement of steel with a non-corroding reinforcement, such as fiberglass-reinforced plastic materials. Much of the current research focuses on the applicability …

Blast Performance of Hybrid GFRP and Steel Reinforced Concrete Beams
… innovative use of blended mixtures of FRP and steel rebar as tensile reinforcement promises to address these limitations through self-centering behavior that provides reductions in residual damage and enhancements in flexural performance. This thesis presents the results of an experimental and …

A mechanistic approach For predicting the effect of various factors on partitioning between free and bound chlorides in concrete
The chloride-induced corrosion of reinforcing steel in concrete structures has become a widespread durability problem throughout the world. When concrete structures come in contact with chloride sources, the chloride ions will diffuse through the body of the concrete and ultimately reach the steel. …

Historic Reinforced Concrete in Alberta: Analysis and Conservation of Two Structures
… of precision in placement of the reinforcing steel (rebar), lack of rebar splice lengths, lack of proper cover of concrete and lack of proper grading and selection of aggregates.

Embedded Antennas In Concrete For Application In Wireless Sensors
… principally as a result of the corrosion of the steel reinforcement that gives these structures their tensile strength. Assessing the condition of steel reinforcement inside the concrete is not simple, since the steel is typically buried beneath one inch or more of concrete. The strain sensor can …

Review of current practices to reduce reinforcement corrosion in concrete structures managed by the City of Cape Town
… structures against concrete deterioration and rebar corrosion have become far more important for road authorities and asset managers. City Engineers are responsible for the repair and rehabilitation of RC structures in different exposure conditions, by identifying the type of deterioration and …

Experimental Program for Fiber Reinforced Polymer Retrofit of Reinforced Concrete Diaphragms
… occurring after yielding of the internal steel rebar. The results highlighted that the overall behavior of the specimens was influenced by the way the retrofit schemes were proportioned and detailed. For example, the application of FRP parallel to the direction of applied shear was found …

In situ Nanoscale Quantification of Corrosion Kinetics by Quantitative Phase Microscopy
… chloride-induced corrosion of A615 low-carbon steel at the nanoscale. Along with surface topography monitoring, a potentiostat was connected to simultaneously monitor the bulk electrochemical activity of the carbon steel. Experiments were conducted in chloride-free and chloride-enriched …

Modellazione dell’instabilità laterale delle barre di armatura nelle pile da ponti in cemento armato
È indubbio che la funzionalità e l’integrità strutturale di ponti, viadotti e sovrappassi costituisca non solo una prerogativa necessaria in fase di esercizio, ma anche in occorrenza di eventi speciali, come ad esempio i terremoti. Le analisi non lineari necessarie a valutare le prestazioni …
