Salinity causes corrosion of reinforcing bars as well as deterioration of concrete. It has gotten views and also has 4.
REPAIR AND REHABILITATION OF STRUCTURES – Question and answer
Discuss about the environment effects which leads to deterioration of concrete structure. Continue with Google or Continue with Facebook. The beam-column joints are particularly prone to defective concrete, if detailing and placing of reinforcement is not done properly.
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? Already Have an Account? Quality of materials, to be used in construction, should be ensured by means various tests as specified in the IS codes. Define physical inspection of damaged structure. Adherence to specified water-cement ratio controls strength, permeability durability of concrete.
What are the possible decisions that can be made after evaluating the strength of a structure? The two facets of maintenance are i Prevention ii Repair 5. Discuss about the design and construction errors leading to deterioration of a structure.
What are the causes of deterioration? Alkali-aggregate reaction and sulphate attack results in early deterioration.
Continue with Google Continue with Facebook. Insufficient vibration may result in porous and honey combined concrete, whereas excess vibration may cause segregation.
In aggressive environme4nt concrete structure will be severely reduces. Micro-cracks present in the concrete are the sources ve2071 ingress of moistures atmospheric carbon notez into the concrete which attack reinforcement and with various ingredients of concrete. What are the steps in repair aspect? EduRev is a knowledge-sharing community that depends on everyone being able to pitch in when they know something.
Clayey materials in the fine aggregates weaken the mortar aggregate bond and reduce the strength. What do I get? How deterioration occurs due to corrosion? Well designed and detailed concrete structure will show less deterioration ce201 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 regularly. Repair is the process of restoring something that is damaged or deteriorated or broken, to good condition.
Discuss about the quality of supervision to be followed at a site. What cs2071 the factors to be considered by the designer at the construction site. Inadequate concrete cover may lead to carbonation depth reaching up to the reinforcement, thus, increasing the risk of corrosion of the reinforcement.
CE Repair And Rehabilitation Of Structures Important 16 Mark Questions | JPR Notes
Jotes with a friend. 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.
Why do I need to sign in? What are the steps in selecting a repair procedure? How can we determine the cause for deterioration of concrete structure? Construction work should be carried out as per the laid down specification.
CE REPAIR AND REHABILITATION OF STRUCTURES Syllabus ~ Online Virtual-Tutor
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 nottes the time of damage may be, obtained.
Define the fixed percentage method of evaluating the strength of existing structure. Rehabilitation is the process hotes returning a building or an area to its previous good conditions. Design of concrete structures governs the performance of concrete structures.
