👉The image illustrates the principles of reinforced and prestressed concrete.
💫It shows how a plain concrete beam bends and cracks under heavy load, and how embedding steel rods enhances its strength.
📌Concrete beams bend and crack under heavy loads because concrete is weak in tension.
📌Reinforced concrete uses embedded steel rods to hold the concrete together and prevent cracking.
📌Prestressed concrete involves stretching the steel rods before the concrete sets, which creates internal compression that makes the beam exceptionally strong and durable.
📌This technique is used in major construction projects, such as the Burj Khalifa.
