Test Method Statements
Brick Compressive Strength & Water Absorption Test
Testing burnt clay bricks for strength and absorption before approval.
Reference standards: ASTM C67
Equipment
- Compression machine
- Oven
- Water tank
- Scale
Procedure
- Pick 10 random bricks per lot.
- Absorption: oven-dry, weigh, immerse 24 hours, weigh again; absorption % = (wet − dry) ÷ dry × 100.
- Strength: fill frogs with mortar, cure, cap, and load to failure.
- Strength = failure load ÷ bed area; average the results.
Acceptance criteria
- First-class bricks typically ≥ 10.3 MPa (1,500 psi) and absorption ≤ 20% — follow project spec.
Health & safety
- Wear PPE: helmet, safety shoes, gloves and eye protection.
