The foundation is in great shape, otherwise. Non-hydraulic lime is produced by first heating sufficiently pure calcium carbonate to between 954 and 1066C, driving off carbon dioxide to produce quicklime (calcium oxide). But adding hydrated lime to the mortar mix can be beneficial. With no Portland in the mix, there is less control over the setting of the mortar.

Use a shovel and cover the lime-water mixture with the sand from the outer edges of the sand pile. Non-hydraulic lime sets by carbonation and so needs exposure to carbon dioxide in the air and cannot set under water or inside a thick wall. This is because type O mortar, after drying, is noticeably weaker than the basic type N. In fact, it is not recommended for load-bearing use due to its meager 350 psi compression strength. I will add my thanks, as well. Thus, in the current study, the inorganic components in the mortar specimens were lime and fine tile dust, and sand was excluded to .

While this type still sees use, it is limited to restoring historic structures due to its extremely low compressive strength. Use of particular mixing techniques can reduce this. WORSE!, some areas have been filled with a masonry caulking. While these ingredients are fairly straight forward, they can be combined in differing volumes to create mortars with differing properties. This was then covered with sand and allowed to sit for a while (from days to weeks) - a process known as 'banking'.

Add about 2/3 of the water to your dry ingredients and mix until even consistency.
