No, Plaster of Paris (POP) is not stronger than cement. They serve different purposes and have distinct properties. Here’s a comparison of their strength and applications:

Plaster of Paris (POP)

• Strength: POP is relatively weak and not designed for structural applications. It has low compressive strength and is more suitable for decorative purposes, such as making molds, sculptures, and false ceilings.
• Setting Time: It sets quickly, typically within 10-15 minutes, but it does not develop the same strength over time as cement does.
• Durability: POP is not water-resistant and is prone to damage from moisture, making it unsuitable for outdoor or load-bearing applications.

Cement

• Strength: Cement, particularly Portland cement, is much stronger than POP and is designed for structural use. It has high compressive strength and is essential for building foundations, walls, roads, and other infrastructure.
• Setting Time: Cement sets slower than POP and continues to harden over time, increasing in strength as it cures (up to 28 days or more).
• Durability: Cement is highly durable, water-resistant, and suitable for both indoor and outdoor applications.

Conclusion

While POP is ideal for decorative and non-structural applications, cement is much stronger and used in construction projects where strength and durability are critical.
