A compression test is a method used to evaluate the strength and durability of materials, particularly in construction and engineering. During the test, a sample material, such as concrete or metal, is subjected to increasing compressive forces until it fails. This helps determine how much load the material can withstand before breaking. The results of compression tests are crucial for ensuring safety and performance in various applications. Engineers use the data to select appropriate materials for structures like buildings and bridges, ensuring they can support the expected loads without collapsing. This process is essential for maintaining structural integrity and safety in construction projects.
