Cement and concrete are vital for modern construction. Cement acts as a binding agent, and concrete offers versatility, durability, and strength. They contribute to sustainable development, are recyclable, energy-efficient, and help reduce carbon emissions. To maintain the construction project's structural integrity and aesthetics, we have prepared a guide to some typical concrete issues, along with their solutions and prevention measures.
1. Cracks:
Identify the type of crack (like shrinkage, settlement, structural) to determine the underlying cause.
- Shrinkage cracks: Thin, straight, caused by concrete drying and shrinking.
- Settlement cracks: Reflect uneven support beneath concrete, often wider at one end.
- Structural cracks: Wider, deeper, caused by excessive loads or foundation movement.
Prevention:
- Proper mix design and adequate curing to minimise shrinkage.
- Use of control joints to manage crack locations.
- Ensure proper subgrade preparation to prevent settlement.
