ABSTRACT
Carefully constructed brick masonry walls, built using earthen mortar are common in vast areas of India (where they coexisted with the most widespread lime mortar masonry) at least until the middle of the nineteenth century. Studies on earthen mortar masonry, though in an embryonic state, already show significant differences compared to the many well studied raw earth buildings. It is believed that this kind of masonry was spread in India, particularly in the Gujarat region. However, the use of local materials and the technological refinement achieved by craftsmen over the years produced heterogeneous applications, also depending on the time period and external influences. In particular, in Ahmedabad, Gujarat, the mixture of earth, sand and quicklime is commonly observed, and this catalogue has documented a basic knowledge of the different types of construction and damages which is currently unavailable in published research.
