An estimation of concrete durability
Recent trends in concrete durability design have favored the use of protective coatings. Although these coatings, if applied correctly, can totally inhibit degradation of the concrete member, these coatings are expensive. In the most severe conditions, the coatings are the only way to avoid …

Geotechnical Problems with Pyritic Rock and Soil
… Consequences of pyrite oxidation include heave, concrete degradation, steel corrosion, environmental damage, acid mine drainage, and accelerated weathering of rock with concomitant effects on strength and stability. Affected disciplines include soil science, mining, engineering geology, …

Concrete deterioration inspection system for extending the operating life of nuclear power plants
This study has evaluated the degradation processes which will potentially affect the reinforced concrete structures of a nuclear power generation facility during and beyond its original design life. This task was undertaken in consideration of the feasibility of extending the life of nuclear power …

Behaviour of massive reinforced concrete sections in seawater
… ultimate life of large offshore reinforced concrete structures. Although much research has focussed on concrete degradation due to chloride ingress, corrosion of permanently submerged concrete is regarded as negligible due to the long-assumed apparent worst case of tidal or splash zone …

Impact of cross section, web reinforcement and load history on the seismic performance of slender concrete walls
Many reinforced concrete buildings in seismic regions employ reinforced concrete shear walls as part of the lateral force resisting system and these walls often have non-planar cross-sectional geometries. To date, the majority of experimental tests on slender concrete walls have been conducted on …

Flexural distress and degradation mechanisms in pretensioned concrete beams and railroad crossties
… component of ballasted railroad track and concrete is a commonly used material for crossties in demanding locations such as heavy axle load (HAL) freight railroads, high-speed rail lines, and rail transit systems. Concrete crossties are often designed as prestressed concrete beams, but …

Examination of the forensic engineering techniques employed on fire-damaged concrete structures
Portland cement (PC) concrete has historically been the most commonly used construction material within the United Arab Emirates (UAE), however, as the demand increases to reduce CO2 emissions most of newly-built facilities make use of modern concrete formulations adopting various PC substitutes, …

Influencia de las condiciones de curado en el comportamiento del hormigón sometido a ciclos hielo-deshielo
… Freeze–thaw process is one of the main causes of concrete degradation in cold regions. In central and eastern Europe, the climatic conditions in the winter season are particularly severe for concrete construction. The successive freezing/thawing cycles cause both external and internal concrete …

Service life extension of reinforced concrete structures using hydrophobic impregnation
… increasing premature deterioration of reinforced concrete structures, mainly due to rebar corrosion, has become a worldwide concern. This has been attributed to insufficient quality and quantity of cover concrete resulting from inadequate mix design and poor onsite workmanship respectively. …
