[PDF] The Cause of Cracking in Post-Tensioned Concrete …

On the premise that "Those who ignore history will be condemned to relive it," this paper attempts to document those types of problems that lead to cracking in post-tensioned concrete box girder bridges and have been encountered in both Europe and the United States. These problems are not limited to those of prestressed box girder bridges, but may occur in other types of structures with

16/7/2020· The modest 4-employee company was the culmination of a year-long investigation by the Andersons throughout Europe to see the few prestressed concrete structures in existence at that time.

Factorial Design Approach in Proportioning Prestressed …

In order to model the effect of mixture parameters and material properties on the hardened properties of, prestressed self-compacting concrete (SCC), and also to investigate the extensions of the statistical models, a factorial design was employed to identify the

Concrete

Concrete can also be prestressed (reducing tensile stress) using internal steel cables (tendons), allowing for beams or slabs with a longer span than is practical with reinforced concrete alone. Inspection of concrete structures can be non-destructive, carried out with equipment such as a Schmidt hammer is used to estimate concrete strength.

Compressive Strength of Concrete & Concrete Cubes | …

Concrete specimens are a cast and tested under the action of compressive loads to determine the strength of concrete. In very simple words, compressive strength is calculated by dividing the failure load with the area of appliion of load, usually after 28 days of curing.

The Extensibility and Micro-Cracking of the In-situ …

The paper describes detailed microscopic investigations of the extensibility and microcracking of the in-situ concrete in composite beams with precast prestressed concrete meers and in-situ reinforced concrete meers. The experimental work included the use

Fibre reinforced polymer materials for prestressed …

Fibre reinforced polymer (FRP) materials are currently used for concrete structures in areas where corrosion problems are serious. Recent appliions of FRP rebars in normal reinforced concrete structures in fact cannot fully utilise the strength of FRP. A more rational use of FRP would be in the area of prestressed concrete (PC) structures. In spite of the superb strength provision of FRP

Repair of prestressed concrete bridges : stress …

With prestressed concrete in particular, it is difficult to anticipate how the stress distribution in an existing structure will be affected by the removal or addition of concrete due to repair work. With the impending implementation of Eurocode in Europe, the development of suitable calculation methods on how to deal with this problem in accordance with the standard scripture, are compelling.
