👉Difference Between CONSTRUCTION Joints and EXPANSION Joints
🔰Expansion joints and construction joints are two types of joints used in concrete construction, but they serve different purposes and have distinct characteristics.
🏷EXPANSION JOINT
⭐️1. PURPOSE : Accommodate thermal expansion and contraction of concrete due to temperature changes.
⭐️2. LOCATION : Typically placed at regular intervals (e.g., 15-20 meters) in long, straight sections of concrete, such as roads, runways,walls, or building floors.
⭐️3. DESIGN/ORIENTATION : Usually consists of a gap (e.g., 10-20 mm) filled with a flexible sealan.
⭐️4. FUNCTION : Allows the concrete to expand and contract without causing stress or damage to the surrounding structure.
🏷CONSTRUCTION JOINT
💫1. PURPOSE : Separate concrete pours, allowing for construction to proceed in stages.
💫2. LOCATION/ORIENTATION : Typically placed at the end of a concrete pour, where the next pour will begin.
💫3. DESIGN : Usually consists of a keyed joint (e.g., a roughened surface) to ensure a strong bond between the two concrete pours.
💫4. FUNCTION : Allows for the construction process to be broken down into manageable sections, while maintaining the structural integrity of the concrete.
