## Answers:

1. A post tension system is a construction technique that uses high-strength steel strands or bars to apply compressive stress to concrete structures. This helps to increase the structural strength and durability of the building.

2. The post tension system works by placing the steel strands or bars inside ducts that are embedded in the concrete before it is poured. Once the concrete has set, the strands are tensioned and anchored at both ends, creating a compressive force that helps to counteract the tensile forces that the structure will face.

3. The benefits of using a post tension system include reducing the amount of concrete and reinforcement needed, allowing for longer spans and thinner slabs, improving structural performance, and reducing the risk of cracking in the concrete.

4. The different components of a post tension system include the steel tendons, anchorage devices, ducts, and stressing equipment.

5. A post tension system is installed by first placing the ducts in the concrete formwork, then placing the steel tendons inside the ducts. Once the concrete has set, the tendons are tensioned using a hydraulic jack and anchored at both ends.

6. Post tension systems are commonly used in Vietnam for bridges, high-rise buildings, parking structures, and industrial buildings.

7. When choosing a post tension system for a project in Vietnam, it is important to consider factors such as the design requirements, budget constraints, the expertise of the construction team, and the availability of materials.

8. In Vietnam, post tension systems are regulated by the Vietnam Building Code and standards set by the Vietnam Association for Standards and Consumers (VASC).

9. Maintenance for post tension systems in Vietnam involves regular inspections of the steel tendons and anchorage devices to ensure they are in good condition and free from corrosion.

10. There are specialized companies in Vietnam that provide post tension system services, offering design, installation, and maintenance of post tension systems for various construction projects.
