Blocks testing involves evaluating the quality, strength, and durability of building blocks such as concrete blocks, clay bricks, or other masonry units. Key tests include compressive strength, water absorption, efflorescence, dimensions and tolerance, soundness, and durability under weathering conditions. These tests ensure that blocks meet industry standards for load-bearing capacity, resistance to moisture, and aesthetic quality, which are crucial for the structural integrity and longevity of buildings. Proper testing of blocks helps identify defects like cracks, porosity, or improper bonding, ensuring they perform effectively in construction projects and comply with safety regulations.
