"Always perform drop and sound tests on arrival to verify optimal curing and compressive durability."
Before laying bricks into mortar, on-site quality checks save immense time and prevent structural cracks. Here are quick, actionable field tests you can conduct immediately on delivery:
- Metallic Ringing Sound: Strike two bricks together; a clear metallic ringing sound indicates thorough curing and dense composition.
- Drop Test: Drop a brick flat from a height of about 1 meter (3-4 feet) onto firm ground. A quality brick will not break.
- Water Absorption: Immerse the brick in water for 24 hours. Quality bricks should not absorb water exceeding 15-20% of their dry weight.
