Generally, concrete structures deteriorate due to the following reasons:
- Corrosion of embedded steel
- Structural damage
- Water infiltration
- Freeze and thaw cycles
- Seismic activity
- Concrete quality and poor workmanship during
- Poor construction, concrete strength
- Environmental conditions
- Design deficiency
- Poor maintenance
- Selection of poor-quality construction materials
Procedure for Structural Protection
Material Science: Material is very important for protection and repairs of civil structures. Many construction chemicals nowadays are present for giving protection and for retrofitting of civil structures. Polymer science is a new advancement in this field.
Conditional Survey/Inspection: It is required to do conditional survey of concrete structures at regular interval/frequency to see the degradation pattern. Structures which are functioning in severe environmental conditions are monitored frequently.
