Bricks testing is vital to ensure the quality, strength, and durability of bricks used in construction. Key tests include compressive strength, water absorption, efflorescence, soundness, shape and size, and material composition. These tests assess the bricks' ability to withstand load, resist water penetration, and maintain stability over time. Proper testing helps identify defective or substandard bricks that could compromise structural integrity, ensuring that only durable and reliable bricks are used in building projects, thereby enhancing safety and longevity.
