Clayey materials in the fine aggregates weaken the mortar aggregate bond and reduce the strength. Quality of materials, to be used in construction, should be ensured by means various tests as specified in the IS codes. Spalling of concrete cover Cracks parallel to the reinforcement Spalling ce207 edges Swelling of concrete Dislocation Internal cracking and reduction in area of steel reinforcement.
Construction work should be carried out as per the laid down specification. Discuss about the design and construction errors leading to deterioration of cw2071 structure. What are the steps in selecting a repair procedure?
Continue with Google or Continue with Facebook. 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. To stop further damages, preventive measure necessary may be planned which may warrent urgent execution. Discuss about the environment effects which leads to deterioration of concrete structure. Rehabilitation is the process of returning a building or an area to its previous good conditions.
REPAIR AND REHABILITATION OF STRUCTURES – Question and answer
Adherence to specified water-cement ratio controls strength, permeability durability of concrete. Define physical inspection of damaged structure.
Alkali-aggregate reaction and sulphate attack results in early deterioration. What is the effect of selecting poor quality material for construction? 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 of noges may be, obtained.
The beam-column joints are particularly prone to defective concrete, if detailing and placing of reinforcement is not done properly. Design of concrete structures governs the performance of concrete structures. Already Ce20071 an Account? Micro-cracks present in the concrete are the sources of ingress of moistures atmospheric carbon di-oxide into the hotes which attack reinforcement and with various ingredients of concrete.
Inadequate concrete cover may lead to carbonation depth reaching up to the reinforcement, thus, increasing the risk of corrosion of the reinforcement.
Discuss about the quality of supervision to be followed ve2071 a site.

How can we determine the cause for deterioration of concrete structure? What are the causes of deterioration? How deterioration occurs due to corrosion? What do I get? Insufficient vibration may result in porous and honey combined concrete, whereas excess vibration may cause segregation.
What are the steps in repair aspect? EduRev is a knowledge-sharing community that depends on everyone being able to pitch in cf2071 they know something. Share with a friend. The two facets of maintenance are i Prevention ii Repair 5. Define the fixed percentage method of evaluating the strength of existing structure.
Why do I need to sign in? In aggressive environme4nt concrete structure will be severely reduces. What are the possible decisions that can be made after evaluating the strength of a structure? Maintenance is the act of keeping something in good condition by checking or repairing it regularly.
