Practical Notes
Paving bricks require significantly higher compressive strength (40 MPa) and lower water absorption than standard building wall bricks to resist abrasion and weathering.
Adequate sub-base preparation is critical in the field, as the bricks rely on uniform ground support to prevent cracking under live loads.
Strict adherence to the 5% water absorption limit is vital to prevent frost damage and long-term degradation in outdoor environments.
