Mortar for Stone Masonry

First mortar used in stone masonry was mud mortar. But now usually, 1:3 cement’s and mortar is used for stone masonry work. For increasing the workability of mortar 15% of cement should be replaced by lime. In order to protect limestones mortar from getting them stained white portland cement mortar should be used. Generally, 1:1:6 (non-staining cement, hydrated lime and six parts clean sand) should be used for stones liable to be stained by cement mortar alone. Non-staining special waterproof cement are also available these days. Rich mortar is used for pointing of stone masonry.
