In Masonry Pre-33 walls, the mortar is described as being composed of which materials?

Explanation:
The key idea is that older masonry used lime-based mortar with sand as the aggregate. In pre-1933 walls, cement wasn’t the binder of choice, so the joints were made with lime mixed with sand, which gives a flexible, breathable bond that tolerates minor movement. There’s also no reinforcing steel embedded in the mortar itself in that era, so the joints contain no rebar. That combination—sand with lime and no cement or rebar—best describes the mortar used in these walls.
