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

What are the factors to be considered by the designer at the construction site. Discuss about the quality of supervision to be followed at a site. jotes

The two facets of maintenance are i Prevention noyes Repair 5. It has gotten views and also has 4. Continue with Google or Continue with Facebook.

In aggressive environme4nt concrete structure will be severely reduces. Insufficient vibration may result in porous and honey combined concrete, whereas excess vibration may cause segregation.

Rehabilitation is the process of returning a building or an area to its previous good conditions. Already Have an Account? Micro-cracks present in the concrete are the sources of ingress of moistures atmospheric carbon di-oxide into the concrete which attack reinforcement and with various ingredients of concrete.

Why do I need to sign in? Continue with Google Continue with Facebook. What are the possible decisions that can be made after evaluating the strength of a structure?

Salinity causes corrosion of reinforcing bars as well as deterioration of concrete. Define physical inspection of damaged structure. By continuing, I agree that I am at least 13 years old and have read and c2e071 to the terms of service and privacy policy. EduRev is a knowledge-sharing community that depends on everyone being able ntes pitch in when they know something.

Some of the use full in formation may be obtained from notees 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 of damage may be, nptes.

How deterioration occurs due to corrosion? Maintenance is the act of keeping something in good condition by checking or repairing it regularly. Alkali-aggregate reaction and sulphate attack results in early deterioration. Clayey materials in the fine aggregates weaken the mortar aggregate bond and reduce the strength.

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

Design of concrete structures governs the performance of concrete structures. Discuss about the design and construction errors leading to deterioration of a structure. What is the effect of selecting poor quality material for construction?

To stop further damages, preventive measure necessary may be planned which may warrent urgent execution. What are the causes of deterioration? What do I get? Adherence to specified water-cement ratio controls strength, permeability durability of concrete.

Construction work should be carried out as per the laid down specification. The beam-column joints are particularly prone to defective concrete, if detailing and placing of reinforcement is not done properly. Repair is the process of restoring something that is damaged or deteriorated or broken, to good condition. Quality of materials, to be used in construction, should be ensured by means various tests as specified in the IS codes.

What are the two facets of maintenance? Inadequate concrete cover may lead to carbonation depth reaching up to the reinforcement, thus, increasing the risk of corrosion of the reinforcement. How can we determine the cause for deterioration of concrete structure? Define the fixed percentage method of evaluating the strength of existing structure. Discuss about the environment effects which leads to deterioration of concrete structure.
