It has gotten views and also has 4. Discuss about the design and construction errors leading to deterioration of a structure.
Adherence to specified water-cement ratio controls strength, permeability durability of concrete. Maintenance is the act of keeping something in good condition by checking or repairing it regularly.
What are the steps in selecting a repair procedure? Construction work should be carried out as per the laid down specification.
In aggressive environme4nt concrete structure will be severely reduces. Continue with Google or Continue with Facebook.
Insufficient vibration may result in porous and honey combined concrete, whereas excess vibration may cause segregation. Why do I need to sign in? What are the steps in repair aspect?
To stop further damages, preventive measure necessary may be planned which may warrent urgent execution. The two facets of maintenance are i Prevention ii Repair 5. Clayey materials in the fine aggregates weaken the mortar nores bond and reduce the strength.
How can we determine the cause for deterioration of concrete structure? Salinity causes corrosion of reinforcing bars as well as deterioration of concrete. Quality of materials, to be used in construction, should be ensured by means various tests as specified in the IS codes. Share with a friend. Well designed and detailed concrete structure will show less deterioration in comparison with poorly designed and detailed concrete, in noted similar condition.
Discuss about the quality of supervision to be followed at a site.
What is the effect of selecting poor quality material for construction? Alkali-aggregate reaction and sulphate attack results in early deterioration.

EduRev is a knowledge-sharing community that depends on everyone being able to pitch in when they know something. Continue with Google Continue with Facebook. Rehabilitation is ce20711 process of returning a building or an area to its previous good conditions. What are the possible decisions that can be made after evaluating the strength of a structure? What are the two facets of maintenance?
REPAIR AND REHABILITATION OF STRUCTURES – Question and answer
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 notds 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 nofes at the design stage and information on the loads acting on the existing structure at the time of damage may be, obtained.
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.
Define the fixed percentage method of evaluating the strength of existing structure. What are the causes of deterioration? Discuss about the environment effects which leads to deterioration of concrete structure. Define physical inspection of damaged structure.
