The mortar mix you see used by layers today contains two ingredients: lime and Portland cement. In fact, the Portland cement ratio is quite high. Old layers used to mix their own mortar on the site by blending lime with Portland cement. Old houses, say over 100 years, rarely had any Portland cement in the mortar.
