3. Which ASTM code is commonly used for prestressed concrete?

1. ASTM stands for the American Society for Testing and Materials. It is an organization that develops and publishes technical standards for a wide range of materials, products, systems, and services. ASTM codes are used to ensure the quality and consistency of construction materials and practices.

2. Prestressed concrete is important because it allows for longer spans and higher load capacities in construction projects. By pre-tensioning or post-tensioning the concrete, internal stresses are introduced to counteract the external loads, resulting in a more efficient and durable structure.
