The mortar with the highest strength is high-strength mortar.
High-strength mortar is typically made with a higher proportion of Portland cement to sand and water. This results in a stronger bond between bricks or blocks.
There are several types of high-strength mortar, each with its unique properties and applications:
- Type M Mortar: The strongest type of mortar, suitable for heavy-duty applications like load-bearing walls and foundations.
- Type S Mortar: Stronger than Type N but not as strong as Type M, often used for masonry walls above ground.
- Type N Mortar: A common type used for general masonry work, offering a good balance of strength and workability.
The strength of mortar is measured by its compressive strength, which is the amount of pressure it can withstand before failing. High-strength mortars have significantly higher compressive strength compared to other types.
While high-strength mortar offers excellent strength, it's important to remember that it is less flexible than other types. This means it might not be suitable for projects where movement is expected, such as earthquake-prone areas.
