No, mortar is not inherently "better" than cement; they serve different purposes. Here's why:
Mortar and cement are often confused, but they are distinct materials with different roles in construction. Cement is a key component of mortar, not the other way around. Let's clarify the differences:
Key Differences Explained
| Feature | Cement | Mortar |
|---|---|---|
| Definition | A fine powder acting as a binder. | A paste used to bind building blocks together. |
| Composition | Primarily clinker, gypsum, and other additives. | Cement, sand, and water (sometimes lime). |
| Main Function | Act as a binding agent in concrete or mortar. | To bond bricks, stones, or blocks in masonry. |
| Strength | Higher when used in concrete. | Lower strength than concrete. |
| Usage | A component in many building materials. | Used in thin layers to join masonry units. |
Mortar's Role
According to the provided reference, while portland cement concrete is one of the most used building materials, masonry mortar is close behind. Mortar is designed to be durable but achieves its strength through finesse rather than brute force. This means that mortar is not meant for thick applications, and its strength is considerably lower than concrete.
Why Mortar is NOT "Better"
- Lower Strength: Mortar's primary purpose is to create a strong bond between blocks, not to be a high-strength structural element.
- Specific Application: Mortar is specifically designed for masonry work, while cement (as a component of concrete) has a broader structural use.
- Flexibility: Mortar's flexible nature accommodates movement in masonry structures, preventing cracking. Cement, when used in concrete, forms rigid structures.
Conclusion
Mortar and cement (used in concrete) are different materials with different purposes. One is not "better" than the other, as they are designed for different applications within the construction industry. Mortar excels in masonry, while cement is a vital binding agent in concrete for more substantial structures. The reference highlights that while mortar is not as strong as concrete, it is still a very widely used building product.
