Question

According to the design standards, the durability of RC structures depends on which important factors?

Answer 1

Durability of structure is defined as the structure should have to resist physicaly, chemically and abrasion during its structurally designed period. RC structures durability depends on the following factors:

1. Structural design : structures are designed to resist all the loads that comes into the structure design during its design life . It is the important factor influencing the durability of structure.

2. Quality of materials: If the quality of materials (steel, cement, bricks etc,)used for construction is very poor/ not as per standards it will affect the durability of structure.

3. Mix proportion parameters : The standard proportions should only used like cement content sand and aggregate content, if any deviations are notified this may affect the durability of structure.

4. Workmanship : Proper workmanship is required to execute the work as per standard procedure.

5. Curing: Curing is the most important factor influencing the durability of structure as this curing gives strength to Concrete and also the structure.

6. Exposure Conditions : Exposure Conditions of structures are divided into severe, extreme, moderate , mild and very severe . Different measures shall be taken to protect the structure other wise it may affect the durability of structure
