How to mitigate thermal expansion issues in large-scale concrete outdoor seating?

Thermal expansion in large-scale concrete outdoor seating can lead to cracks, structural damage, and reduced longevity. To address this, consider the following strategies:

1. Expansion Joints: Incorporate properly spaced expansion joints to allow concrete to expand and contract without stress buildup.

2. Material Selection: Use low-thermal-expansion aggregates or fiber-reinforced concrete to minimize movement.

3. Temperature Control: Pour concrete during moderate temperatures and use curing blankets to regulate heat.

4. Proper Reinforcement: Steel rebar or mesh can help distribute stress and prevent cracking.

5. Slab Thickness: Optimize slab thickness to balance strength and flexibility.

By implementing these measures, you can enhance durability and maintain the aesthetic appeal of outdoor concrete seating.
