What are the factors to be considered by the designer at the construction site. The beam-column joints are particularly prone to defective concrete, if detailing and placing of reinforcement is not done properly.

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 causes of deterioration? What are the two facets of maintenance? How deterioration occurs due to corrosion?

Continue with Google or Continue with Facebook. EduRev is a knowledge-sharing community that depends on everyone being able to pitch in when they know something. Quality of materials, to be used in construction, should be ensured by means various tests as specified in the IS codes. What is the effect of selecting poor quality material for construction? Inadequate concrete cover may lead to carbonation depth reaching up to the reinforcement, thus, increasing the risk of corrosion of the reinforcement.

Spalling of concrete cover Cracks parallel to the reinforcement Spalling at edges Swelling of concrete Dislocation Internal cracking and reduction in area of steel reinforcement. Alkali-aggregate reaction and sulphate attack results in early deterioration. What are the steps in repair aspect?

Insufficient vibration may result in porous and honey combined concrete, whereas excess vibration may cause segregation. Design of concrete structures governs the performance of concrete structures. ce22071

Clayey materials in the fine aggregates weaken the mortar aggregate bond and reduce the strength. Continue with Google Continue with Facebook.

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

Why do I need to sign in? Ce201 can we determine the cause for deterioration of concrete structure? Discuss about the design and construction errors leading to deterioration of a structure.

Already Have an Account? In aggressive environme4nt concrete structure will be severely reduces. Adherence to specified water-cement ratio controls strength, permeability durability of concrete.

Define physical inspection of damaged structure. Maintenance is the act of keeping something in good condition by checking or repairing it regularly.

What do I get?

Construction work should be carried out as per the laid down specification. Micro-cracks present in the concrete are the sources of ingress of moistures atmospheric carbon di-oxide into the notez which attack reinforcement and with various ingredients of concrete.

By continuing, I agree that I am at least 13 years ce22071 and have read and agree to the terms of service and privacy policy. Repair is the process of restoring something that is damaged or deteriorated or broken, to good condition. What are the possible decisions that can be made after evaluating the strength of a structure?

REPAIR AND REHABILITATION OF STRUCTURES – Question and answer

To stop further damages, preventive measure necessary may be planned which may warrent urgent execution. Rehabilitation is the process of returning a building or an area to its previous good conditions. It has gotten views and also has 4.

Define the fixed percentage method of evaluating the strength of existing structure. 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 ntes structure at the time of damage may be, obtained.

Share with a friend. Discuss about the quality of supervision to be followed at a site. fe2071

Discuss about the environment effects which leads to deterioration of concrete structure. The two facets of maintenance are i Prevention ii Repair 5. What are the steps in selecting a repair procedure? Salinity causes corrosion of reinforcing bars as well as deterioration of concrete.
