REPAIR AND REHABILITATION OF STRUCTURES – Question and answer
Define physical inspection of damaged structure. To stop further damages, preventive measure necessary may be planned which may warrent urgent execution.
What is the effect of selecting poor quality material for construction? Well designed and detailed concrete structure will show less deterioration in comparison with poorly designed and detailed concrete, in the similar condition. Maintenance is the act of keeping something in good condition by checking or repairing it c2e071.
Discuss about the design and construction errors leading to deterioration of a structure.

What are the steps in repair aspect? Discuss about the environment effects which leads to deterioration of concrete structure.
Clayey materials in the fine aggregates weaken the mortar aggregate bond and reduce the strength. Notds are the factors to be considered by the designer at the construction site. How deterioration occurs due to corrosion?
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? What are the steps in selecting a repair procedure?
EduRev is a knowledge-sharing community that depends on everyone being able to pitch in when they know something.
Continue with Google or Continue with Facebook. Why do I need to sign in? Spalling of concrete notfs Cracks parallel to the reinforcement Spalling at edges Swelling of concrete Dislocation Internal cracking and reduction in area of steel reinforcement.
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.

It has gotten views and also has 4. Adherence to specified water-cement ratio controls strength, permeability durability of concrete. Salinity causes corrosion of reinforcing bars as well as deterioration of concrete. Define the fixed percentage method noes evaluating the strength of existing structure.
Alkali-aggregate reaction and sulphate attack results in early deterioration. Design of concrete structures governs the performance of concrete structures.

Already Have an Account? The two facets of maintenance are i Prevention ii Repair 5. In aggressive environme4nt concrete structure will be severely reduces. 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. How can we determine the cause for deterioration of concrete structure? Continue with Google Continue with Facebook.
Rehabilitation is the process of returning a building or an area to its previous good conditions. 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 cr2071 classification etc, their causes preparing and documenting the damages, collecting the samples notfs laboratory testing and analysis, planning for in situ testing, special environmental effects which have not been considered at the design stage and information on notss loads acting on the existing structure at the time of damage may be, obtained.
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 notse done properly. Discuss about the quality of supervision to be followed at a site.
