Tag: prestressed concrete Conclusions Degradation of prestressed concrete

All over the world serious damage in post- and prestressed components has occurred due to stress corrosion cracking of prestressed steel during the past 40 years. Because the associated design, execution and building materials used were not unusual this problem has caused great concern. An important factor is that prestressed steel is unable to withstand the combined effects of variable

Tag: prestressed concrete Degradation of prestressed concrete Introduction

Most of the prestressed concrete structures built during the last 50 years, where design and construction have adhered to best practice, have proved to be highly durable.1,2 Analysing the incidence of occasional problems has confirmed that serious failures are rare in proportion to the volume of prestressing steels used worldwide. During the past 40 years, there have been isolated examples
