What components make up a 1:1:6 mix?

In a 1:1:6 mix, the components consist of 1 part Portland cement, 1 part hydrated lime, and 6 parts sand. This specific mix ratio is significant in masonry because it is designed to create a mortar that has good workability and adhesion properties.

Portland cement is essential for binding the materials together, while hydrated lime enhances the plasticity and workability of the mixture, allowing for easier trowel application and better moisture resistance after setting. The large proportion of sand helps provide bulk and reduces shrinkage when the mortar cures.

This particular combination is commonly used in masonry construction due to its balance of durability and ease of application, which is important for achieving strong and lasting joints between masonry units. Other options may include variations that do not yield the same balance of properties necessary for effective masonry work.
