Since last decade Reinforced concrete structure have suffered a lot. Some of them show this problem over a period of time and some of them shown relatively short service time. Its not true that a good concrete does not need maintenance, of course it does need investigation, maintenance treatment accordingly.
Its an requirement of the site engineer to take care of some of the climate condition, neglecting which can get serious long-term problem. Another would be lack of awareness to the owner about the maintenance and treatment of the concrete structure.
In this article we are going to learn about the different situation of concrete structure that we need to call for investigation as title suggested.
What are the Causes of Damage of Structure
- Design and Construction Flaws
- Usage of poor quality material
- Environmental effect
- Deterioration due to corrosion
- Quality of supervision
Call for Investigation
In order to call for investigation for a structure damage first we need to know the understand the damage in structure. Most common way to do is physicals/visual inspection of damaged structure.
When the structure is damaged the normal visual signs are : cracks which is the most common one, different patterns and size, rust spot or rust stain, peeling of plasters, spalling of concrete, swelling of concrete, chemical attack and corrosion reinforcement if exposed.
The very next job is to know whether the damage is structural or non structural. Some use full information may be obtained from the physical inspection of the damage structure, like nature of distress, type of distress, extent damage and its classification etc., preparing and documenting the damage.
Collecting the sample in order to take to the laboratory for testing and analyzing the further damage, getting the sample ready for in situ testing which is specially done for environmental effect if this has not been consider at the design stage. and the information of loading on structure at the time of damage. necessary action need to be taken in order to prevent the further damage of structure.
How We Can Prevent Damage Of Structure
First thing to keep in mind that it is possible to cast a good concrete structure which has durability and less maintenance with some of the precaution has to be take at the correct time.
The practice of a systematic investigation of the structure placed in aggressive environments permits both the detection of dangerous situations of damage, and the decision to undertake immediate measures of intervention with the aim to prevent causalities, important material losses, technological accidents or undesired ecological effects, as well as to stop accelerated deterioration processes on the members/structures.
When making a diagnosis concerning intervention measures for the rehabilitation of the structures exposed to aggressive environments, one must consider not only the effect on the building materials (concrete, reinforcement), but also the on the broader issues of design and execution of intervention works for different categories of structures
The construction has to regarded and analyzed as a whole, taking into account its initial design.
In order to keep concrete structure a long lasting and durable we must need to keep an on three things
Maintenance: Which is an act of keeping something in good condition by checking it regularly.
Repair: It is the process to restored something which is damaged to good condition and
Rehabilitation : It the process of returning a structure or building in its original good condition.
