REPAIR AND REHABILITATION OF STRUCTURES – Question and answer Civil Engineering (CE) Notes | EduRev

To stop further damages, preventive measure necessary may be planned which may warrent urgent execution. Construction work should be carried out as per the laid down specification.

What are the factors to be considered by the designer at the construction site. In aggressive environme4nt concrete xe2071 will be severely reduces. Continue with Google or Continue with Facebook. By continuing, I agree that I am at least 13 years old and have read and agree notex the terms of service and privacy policy. What are the possible decisions that can be made after evaluating the strength of a structure?

The beam-column joints are particularly prone to defective concrete, if detailing and placing of reinforcement is not done properly. Share with a friend. How deterioration occurs due to corrosion?

It has gotten views ve2071 also has 4. Adherence to specified water-cement ratio controls strength, permeability durability of concrete. Define the fixed percentage method of evaluating the strength of existing structure.

Discuss about the design and construction errors leading to deterioration of a structure. Quality of materials, to be used in construction, should be ensured by means various tests as specified in ec2071 IS codes. Clayey materials in the fine aggregates weaken the mortar aggregate bond and reduce the strength. What are the causes of deterioration?

What are the steps in selecting a repair procedure? Continue with Google Continue with Facebook. What are the steps in repair aspect?

Well designed and detailed concrete structure will show less deterioration in comparison with poorly designed and detailed concrete, in the similar condition.

The two facets of maintenance are i Prevention ii Repair 5. Micro-cracks present in the concrete are the sources of ingress of moistures atmospheric carbon di-oxide noges the concrete which attack reinforcement and with various ingredients of concrete.

Some of the use full in formation may be obtained from the physical inspection of damaged structure, like nature of distress, type of distress, extent damage and its classification etc, their causes preparing and documenting the damages, collecting the samples for laboratory testing and analysis, planning for in situ testing, special environmental effects which have not been considered at the design stage and information on the loads acting on the existing structure at the time ce207 damage cee2071 be, obtained.
