A compression test is a method used to evaluate the strength and durability of materials, particularly in construction and engineering. During this test, a sample material, such as concrete or metal, is subjected to a controlled compressive force until it fails. The results help determine how much load the material can withstand before breaking, which is crucial for ensuring safety and performance in structures. This test is commonly performed on materials like concrete, steel, and wood to assess their mechanical properties. Engineers use the data obtained from compression tests to inform design decisions and ensure that structures can support the expected loads throughout their lifespan.
